The Science of Greyhound Race Prediction by Guy Slade

It's not a Game? It's a Science!

Hello, welcome and thank you for visiting

I enjoy following the Open Racing held here in Great Britain & Ireland and am a keen collector of greyhound memorabilia, mainly old race programmes! I've also attended meetings in America and Australia.

In this article, I explain how to predict dog races using Greyhound Predictor Software and discuss the relevant formlines and statistics required to be entered into the Race Predictor Stat Screen.

Please feel free to contact me if you have any questions?

The Science of Greyhound Race Prediction - Introduction

Greyhound Racing in the 21st Century allows you to bet on-line, combine this with RPGTV live race streaming, Betting Shop TV and the ever increasingly popular number of dog racing websites; never before have we experienced such a revolution in greyhound information and technology!

Although, I firstly recommend you acquire a good 'sporting newspaper' like the "RACING POST" with full in-depth coverage of all today's meetings.

Greyhound Predictor Version 2.0 lets you predict races run over three standard distances: 515 metres (563 yards), 500m (547y) and 480m (525y). After studying the racing form in your newspaper or on the internet, please select a race you wish to predict!

If you haven't yet downloaded and installed Greyhound Predictor then please click here to download a free trial.

Please note: the full registered version will not display the dialogue boxes or be limited to only one race per start-up.

Now double click the Crystal Ball icon on your desktop. Click I Agree and Press Spacebar to move through the information screens.

Once the Main Menu has loaded you can select Predictor, Betting Lounge, Gallery, Information or the Option Menu by using the Up / Down cursor keys. If you have any difficulties veiwing our Greyhound Racing Software, please see support page for further information.

By selecting the Option Menu you can alter the number of runners and change 'distances' into metres or yards or 'weights' into kilos or pounds!

Alternatively, find the Configuration Utility on your computer (Start - Programs - Greyhound Predictor v2.0 - Configuration) to preset your own 'race settings' mentioned above as the default mode of your choice. Each time a maximum six or eight dogs will only then be saved for you!

As Greyhound Predictor v2.0 always runs in Full Screen Mode! You may require two seperate monitors when entering formlines from the internet.

Now are you ready to start predicting races?

Now select Predictor to navigate throughout simply highlight your answers by using the Left / Right Cursor Keys and Press Spacebar to continue. You will be asked to answer ten race-form questions for each runner, although the first three questions only apply to individual race set-ups.

1 - Race Grade

In this section, I mention famous greyhound races in Great Britain & Ireland and their associated track venues. I include information on race speeds, classic winners and affiliated trainers and compare English dog racing grades with Irish, American and Australian grading systems.

Grade of Race?

Greyhound Predictor v2.0 Software allows you to simulate four race grades: Open Race, Top Grade, Middle Grade and Low Grade.

In England an 'open race' (form statistic OR) represents the highest standard of racing grades and consists of two divisions - Major Open Races - Category One, Two, Three and Minor Opens. In Ireland the best middle-distance races are called AAO's. In America these contests are known as RSA's or SA's (Racing Secretaries A Class). In Australia all major competitions are classified as Group Races and generally referred to as FFA's (Free for All).

UK Category One - Open Racing - Major Greyhound Racing Events and Race Venues

Out of all the 'classic races' held annually, the English Derby - won 29/06/19 by Priceless Blake trained by Paul Hennessy (IRE) - (Nottingham) originally staged in 1927 at the White City Stadium, London, still remains today the most important competition. This years event run over the Derby distance of 500 metres was sponsored by Star*Sports, Arena Racing Company (Arc) and Local Parking Security (LPS) and carried a winner's prize of £100,000!

Other 'national derbies' include the Scottish Derby - won 04/05/19 by Braveheart Bobby trained in Ireland by Pat Buckley - (Shawfield) first held at Carntyne, Glasgow in 1928. Other famous Scottish races include the St Mungo Cup - (Shawfield) and Edinburgh Cup previously staged at Powderhall Stadium. The Welsh Derby first run from 1928 - 1937 at the White City, Cardiff and then from 1945 - 1977 at the old Cardiff Arms Park sadly no longer takes place. The Trigo Cup formerly known as the Ulster Derby first held in 1929 at Celtic Park, Belfast was reinaugerated in 2010 as the Northern Irish Derby - (TBC).

Along with the derby, the English Oaks - won 22/12/18 by Ravenswood Flo trained at Monmore by Kevin Hutton - (Swindon) a race confined to bitches first run in 1927 at the White City, London, are the two oldest Classics. Last years race kindly sponsored by John Turner carried a winner's prize of £15,000.

The St Leger run from 1928 - 1998 at the old Wembley Stadium is the oldest 'stayers classic' but unfortunately last year only carried a winners purse of £5,500 - won 17/12/18 by Calico Ranger trained at Henlow by Carol Weatherall - (Perry Barr). The 2019 St Leger now sponsored by RPGTV will carry a first prize of £15,000.

Other famous races include: All England Cup and Laurels - (Newcastle), Arc and Produce Stakes - (Swindon), Golden Jacket, Gold Collar & Kent St Leger - (Crayford), Golden Sprint, Champion Stakes and Essex Vase - (Romford), Lowther Stakes, Eclipse and British Breeders Stakes - (Nottingham), Scurry Cup - (Belle Vue), Regency, Sussex Cup, Olympic and Winter Derby - (Brighton & Hove).

The 2018 Trainers' Title was won for a record tenth time by Mark Wallis attached to Henlow and based at the 'Imperial Kennels' Lakenheath, Suffolk.

Only the top six handlers qualify for the Trainers' Championship (TC) "finals night" held this year 06/04/19 at Owlerton Stadium, Sheffield and won by Angela Harrison. Selected race winners included: Gain GTA Sprint 280m - Lost One Dare (Kevin Hutton), Puppy 480m - Chicago Fire (Kevin Hutton), Bitches 480m - Seaglass Celine (Patrick Janssens), Standard 480 - Droopys Trapper (Angela Harrison), Standard Division (A) 500m - Droopys Verve (A Harrison), Standard (B) 500m - Droopys Expert (A Harrison), Stayers (A) 660m - Ridgedale Max (Phil Simmonds) and Stayers (B) 660m - Antigua Fire (Mark Wallis).

Other Invitational races (IV) include the 2019 Racing Post Juvenile - (Sheffield), Derby Invitation, Select Stakes and Select Stayers - (Nottingham), East Anglian Derby Invitation - (Yarmouth) and the odd Showdown - 'swan vesta' Match Racing (M) limited to only two dogs.

Minor Open Races include all "one offs" with a minimum of £100 to the winner. Maiden Opens are limited to greyhounds yet to win an Open Race.

Irish Greyhound Racing

As from 31st March 2014 the Irish Greyhound Board (IGB) has implemented new race grading bands. For 525 yard races all dogs recording a time less then 28.49 seconds will be classed as AAO, 28.50s - 28.69s = AO, 28.70s - 28.89s = A1 up to and including 30.50s - 30.70s = A10.

The 2018 Boylesports Irish Derby - won 22/09/18 by Ballyanne Sim trained by James Robinson - (Shelbourne Park) first run in 1932 is the most prestigious event in the racing calendar with a winner's purse of €140,000. Although originally preceded by the 'National Derby' first held in 1928 at Harolds Cross.

Famous races include the Easter Cup first staged in 1928, Irish Oaks first held at Clonmel in 1932, Champion Stakes and Gold Cup - (Shelbourne Park - SPK). The Irish St Leger first run at Celtic Park, Belfast in 1932 - (Limerick - LMK), Laurels - (Cork - CRK), Produce Stakes - (Clonmel - CML), Irish Sprint Cup - (Dundalk - DLK), Longford Derby - (Longford - LGD), Newbridge Oaks - (Newbridge - NWB), Cesarewitch - (Mullingar - MGR), Race Of Champions - (Tralee - TRL), Select Stakes and Munster Oaks - (Waterford - WFD) etc.

Invitational races include The Dundalk International - won 12/07/19 by Killmacdonagh trained in Ireland by Kieran Lynch - (Dundalk). There are also Irish-Anglo and Irish-American challenges - (Shelbourne Park). Throughout the year 'festivals of racing' take place at Clonmel, Galway, Lifford, Limerick etc.

Shelbourne Park hosted their 7th annual "Night Of Stars" special gala meeting (17/11/18) with eight races carrying a winner's cheque of €10,000 and included the following category winners: Open 350 - Ardnasool Jet (Cathal McGhee), Open 525 Bitches - Vancouver (Peter Cronin), Open 525 Dogs - Cabra Hurricane (Patrick Guilfoyle), Open 550 - Slippy Cian (Graham Holland), Open 575 - Lenson Blinder (Graham Holland), Open 600 - Macaroon Cruz (Graham Holland), 750 - Towcester Story (Brendan Mathews), and 850 - Are Nagini (Liam Dowling).

In Ireland puppies begin their racing careers in Novice grade (N0 - N3) although, some may also compete in open competitions for greyhounds unraced! The most valuable being the Connolly's Red Mills Unraced - (Curraheen Park) with a winner's cheque of €16,000! Although, the Con & Annie Kirby Memorial - won 20/04/19 by Toolmaker Josie trained by Robert Gleeson - (Limerick) with a first prize of €80,000 remains the world's richest puppy race!

Greyhound Racing Speeds

The very fastest greyhounds average speeds around a circuit close to 40 mph / 64.37 kph! Although 'top speeds' may only be achievable on first class 'galloping tracks' with big circumferences, long racing straights and wide sweeping cambered bends!

The quickest time run over 515 metres is 28.88 seconds set 25/01/01 by Australian "wonder dog" Brett Lee trained by Darren McDonald from Peacedale, Victoria in the Adelaide Cup held at Angle Park, South Australia (circumference 457 metres) and represents an average speed of 39.89 mph / 64.20 kph!

Interestingly, the fastest UK time for 515 metres is 29.20 secs set 31/07/07 by "brilliant Barney" Barnfield On Air trained by Sam Poots (Retired) in the Sussex Cup run at Brighton & Hove greyhound stadium (circumference 455 metres) and represents an average cruising speed of 39.45 mph / 63.49 kph. The best time achieved by a bitch is 29.54 secs set by Bridge Ruth trained by Mark Wallis (38.99 mph / 62.76 kph) when winning the 2013 Brighton Belle. Although this time was equalled 31/08/17 by "2018 bitch of the year" Donation trained by Heather Dimmock in a heat of the 500 Ladies.

The 2019 English Greyhound Derby held at Nottingham (circumference 437m) was recently 25/05/19 set alight by Skywalker Logan trained in Ireland by Patrick Guilfoyle after breaking Sawpit Sensation's previous record by eleven spots when recording 29.05 secs (38.45 mph / 61.96 kph) in 1st round heat. The fastest time achieved by a bitch was 29.27 secs (38.21 mph / 61.50 kph) by Queen Beyonce trained by Rab & Liz McNair at Central Park. Although, Ballymac Tas trained by Liam Dowling (IRE) became the first bitch since Dilemmas Flight in 2007 to reach the final, finishing runner-up!

The English Derby record for 500 metres is 28.72 secs set 09/06/17 by Tyrur Shay trained in Ireland by P J Fahy in 2nd round heat held at Towcester (circumference 420 metres) and represents an average racing speed of 38.89 mph / 62.59 kph.

The old Derby record for 480 metres - Wimbledon (circumference 414 metres) was broken 30/05/15 by Eden The Kid "2015 British Bred of the Year" trained by Elizabeth & Rab McNair when posting 27.95 secs (38.42 mph / 61.83 kph) in 1st round.

The English 480 metres record is 27.32 seconds recorded 06/08/14 by Candlelight King trained locally by Elaine Parker in a British Bred race held at Owlerton Stadium, Sheffield (circumference 425 metres) averaging 39.31mph / 63.74 kph.

The Scottish Derby 480 metres record was lowered again by Droopys Buick trained by Angela Harrison & Jimmy Wright when recording 28.55 secs in semi-final ran 29/04/17 at Shawfield (circumference 432m). Although surprisingly the average speed is only 37.61 mph / 60.52 kph!

The Irish Derby record for 550 yards (503 metres) - Shelbourne Park (circumference 425 yards) was achieved 17/08/17 by Sonic trained by Graham Holland (IRE) when posting 29.12 secs in Boylesport Derby 1st round - (38.63 mph / 62.17 kph). In the 2018 Derby final Ballyanne Sim recorded 29.28 secs and was the quickest time ever run in an Irish Final. Although, the track record is still held by Tyrur Van Gaal trained by PJ Fahy (IRE) 27/08/15 when recording 29.10 secs (38.66 mph / 62.20 kph) in the Ger McKenna / Seamus Graham Memorial Plate!

The fastest run in Ireland over 525 yards was sensationally achieved by Paradise Madison trained in County Meath by Oliver Bray when stopping the clock at 27.67 seconds in the semi-final of the Comerford Cakes National Puppy Stake held 08/12/12 at Shelbourne Park (38.81 mph / 62.46 kph). The fastest time recorded by a bitch is 27.70 secs set 25/05/19 by Ballymac Arminta trained in Ireland by Liam Dowling (38.77 mph / 62.39 kph) in the 2019 Sporting Press Irish Oaks!

The 525 yards record was once held by Catunda Harry trained by Owen McKenna (IRE), who became the first greyhound to dip under 28 secs on an Irish track, when recording 27.99 secs in a heat of the Ballygodoon Stud Puppy Stakes run 17/06/07 at the old "Market Fields" track at Limerick.

The Northern Irish 525 record is 27.88s (38.52 mph / 61.99 kph) set 23/10/10 by Leeveiw Jet (Graham Holland) in the Tennants Gold Cup - (Drumbo Park - DBP).

In Australia at Capabala in Brisbane, Upper Class Lad trained by John Catton (Mount Cotton) running in the Michael Miller Memorial Cup (03/10/15) over a straight grass track recorded 19.28 secs for 366 metres / 400 yards - averaging 42.46 mph / 68.34 kph and is claimed to be a WORLD RECORD SPEED! Although, speed tests conducted by Towcester Racecourse using a hi-tech transponder system taken from dogs competing in the 2017 English Derby, interestingly revealed split-second acceleration speeds approaching 50 mph / 80.47 kph!

Hurdle Racing

Other standard race grading prefixes that indicate to the type of race include: (H) = Hurdle and (CH) = Chase - two extra hurdles are added.

The first English race over hurdles took place at Belle Vue, Manchester at its opening meeting on the 24th July 1926 - won by Melksham Autocrat.

The most prestigious races consist of the English Grand National - won 28/04/19 by Caislean Fifi trained at Hove by Seamus Cahill - (Central Park) first run at the White City, London, and Irish Grand National - won 09/12/18 by Lightning Prince trained by Pat Kiely - (TBC) both inaugerated in 1928.

Category One hurdle races include the Springbok - won 03/03/19 by Burgess Brandy trained by Rick Holloway - (Central Park) and Champion Hurdle - won 02/06/18 by Lenson Wilson - (Towcester) - first run at White City in 1927. Due to the loss of Towcester, all major hurdle races in 2019 will be staged at Central Park with track promoter Roger Cearns putting up a bonus £10,000 for any dog to win all three races.

Cornamaddy Jumbo trained by Mark Wallis was voted "2014 Hurdler and Greyhound of the Year" when becoming the first ever dog to complete the 'English triple crown' by winning all three Category One's - the Springbok, Grand National and Champion Hurdle in the same year!

Other events include the Jimmy Jupp National Hurdle - (Hove), Kent County Hurdle and Boxing Day Chase - (Central Park), Chief Ramsbottom Hurdle, Dual Distance and Kent National Hurdle - (Crayford), Champions Night Hurdle and Roger Kent Barton Triumph Hurdle - (Romford), Rockybay Munster Hurdle - (Curraheen Park) etc.

Occasionally a greyhound will be given a 'hurdle handslip' not released from the traps but usually 'hand slipped' along the straights in order to gradually introduce them to jumping hurdles. Please note: any runner having competed in a hurdle race or schooling trial and was subsequently switched back to race on the flat, is always considered a good sign! as the hurdles tend to concentrate a dog's mind on its racing and therefore sharpens them up!

Graded Racing

The vast majority of dog races around the world are known as 'Graded Races' (GR's). Middle-Distance grades include:

U.K. - Top Grade - (A1 - A3) equilavent to American greyhound grades (A, B) and Australian grades (1, 2). Some of these 'top graders' may also compete in major open race events and can average speeds around a track between 38-39 mph.

U.K. - Middle Grade - (A4 - A6) equilavent to American grades (C, D) and Australian grades (3, 3/4, 4). Occasionally 'graded runners' competing at the best "city tracks" maybe the equal of 'A1' graded dogs running at lesser not so good "country tracks". These hounds can average speeds between 37-38 mph.

U.K. - Low Grade - (A7 - A11) equilavent to American grades (E, F and Maidens) and Aussie grades (4/5, 5 and Maidens). Most greyhounds will start or finish their racing careers in the lower grades and generally record speeds between 35-37 mph.

U.K. - B Grade - (B1 - B6) This grade prefix indicates to either a slightly shorter or slightly longer standard distance.

Knowing the grade is very important, as it's an approximation to the expected level of performance and therefore indicates to the overall race standard. Generally, I consider a greyhound's grade should reflect past performances and be relative to previously recorded racetimes!

When fully fit 'Graders' tend to run more frequently than 'Open Racers' and usually compete in a race once a week, although twice and sometimes three times is not uncommon. However, any dogs thought 'over raced' will often see a decline in racing form and may need a rest to freshen them up!

The Greyhound Welfare Graded Derby previously held at Towcester 02/09/17 with a winner's purse of £10,000 was the richest graded dog race in England. In Ireland the most valuable being the Lee Strand 550 (A3) held 19/05/18 at Tralee with a first prize of €8,500.

At the GBGB annual awards ceremony held in London 27/01/19, Swift Keeper trained at Monmore by Mel Baker, owned by Abie Knowles and bred for consecutive years by Ian Greaves was voted "2018 Graded Racer of the Year" after starting in A8 grade and finishing up with three A1 victories!

Puppy and Veterans are represented by a standard prefix: (P) = Puppy (V) = Veteran. Famous races include the Senior's Derby - (Peterborough).

Other types of racing grades that may take place during a meeting include: (KC) = Kennel Championships, (KS) = Kennel Sweepstakes, (IT) = Intertrack Racing, (Hcp) = Handicap Racing and the extremely rare (QS) = Quickstakes - 2 or 3 semi-finals take place with the final being held at the same meeting.

All 'Punters' when studying graded raceform will face the dilemma of not knowing whether to back a good dog 'lowered in class' running badly or a not so good dog 'raised in class' running well? "If only I had a crystal ball" I hear you say!!

Successfully predicting Graded Races (GR) will invariably be more challenging than forecasting Open Races (OR), as the 'grader' generally grades the races very closely with only minute differences in time to choose between the runners.

Therefore, to obtain the best results from the 'Predictor' I suggest choosing UK OR's, Irish AAO's, American SA's or Australian FFA's, as the runners in these top greyhound grades are not only more consistent, but also allow "canine superstars" to compete with much greater differences in racing ability. This can be most noticeable during the early rounds of major competitions and theoretically makes the 'open grade' more predictable than a graded race. Although, these differences in the dog's standards will always no doubt be reflected in the individual prices quoted as the odds of a race!

For 'Greyhound Predictors' wishing to simulate dogs 'raised or lowered' in grade, then one of the best ways to represent a change in grade would be to alter a dog's time! For example, if you consider a grey to be 'upped in class' then you should perhaps add on between 0.10 - 0.20 secs to their fastest time, as up-graded dogs theoretically, are less likely to obtain a trouble free run in a race in order to produce their quickest times. Although, often to the contrary, certain strong 'improving greyhounds' may actually appreciate a quicker overall travelling speed throughout a race and will be towed along in the 'faster slipstreams' of other initially speedier dogs and despite being 'raised in class' will continue to improve their best times. For further information please see Racetimes.

Alternatively, if you wanted to simulate down-graded dogs then you should perhaps deduct between 0.10 - 0.20 secs from their fastest time, as all dogs 'lowered in class' theoretically, have a better chance of obtaining more 'racing room' to improve their quickest times, and indeed yes, you may deduct an appropriate amount of time that best simulates greyhounds dropped in grade.

I should also like to mention in the interests of 'The Science of Greyhound Race Prediction' that since the dogs themselves remain completely unaware of the racing grade their running in or have previously competed at, then you may wish to leave a dog's fastest time as it is, the choice is always yours!

Now check the formlines, the stat grade of race is found at the top of each race heading.

Now select the correct grade category and Press Spacebar to enter.

2 - Track Condition

In this section, I explain how different track conditions affect the performances of dogs with various running styles and why this may alter your future race predictions. Please see: English Track Circumferences, Hare Types and Surfaces. Greyhound Predictor v2.0 Track Dimensions are also provided.

Track Condition?

An understanding of how the weather affects the surface of a greyhound track is the key to answering this question, the ability to predict accurately in advance the correct going conditions? or state of the track? is indeed a vital element that should always be considered when predicting races.

The vast majority of greyhound races worldwide are run on sand tracks, although originally many of todays' prestigious racing events were first held on grass tracks. Other surfaces used include the 'loam tracks' seen in Australia and not to forget the old 'cinder tracks' of greyhound racing's historical past.

All greyhound establishments will try to maintain a fair and safe circuit for racing by regularly rolling flat and watering the sand. However, this can often be a difficult task to achieve as 'track-surfaces' are constantly affected by adverse weather conditions. Therefore, any dogs fortunate to race on a faster surface then their competitors, theoretically can produce quicker times! This 'advantage' or alternatively considered 'disadvantage' in the bias of the track is very significant as it not only affects results but also influences any betting in a race!

I suggest the 1st thing all "Predictors" should do while attending a greyhound meeting is to check the condition of the track! This is a major advantage in selecting winners given to all race-goers! Although, there are still three possible ways for 'off track punters' to correctly calculate the going conditions. Firstly, by paying attention to local weather forecasts for any 'climatic changes' due to affect the race surface. Secondly, you may notice a repetitive pattern to 'previous trends' of winning trap numbers reflected in past results. Or thirdly, by studying the 'win times', 'racing lines' and 'running styles' of all the winners from earlier races, then decide if it's the inside, middle or outside traps if any, that has the advantage on those particular surface conditions.

Greyhound Predictor Software allows you to simulate four race conditions:

Fast Track - [+0.40 secs = GP state of going adjustment] - All greyhounds racing in hot sunny atmospheric temperatures can produce very quick times, as these race conditions generally favour the 'inside runners'. It is usually on 'faster ground' in the summer months that track records maybe broken, although a hard frozen track in mid-winter may also be considered to be running fast and overall benefits the 'quick away runners'!

Normal Track - [0.00 secs] - Dogs racing on a normal surface should produce normal race and sectional times. This type of going should always be considered fair to all racing lines and running styles of greyhounds.

Slow Track - [-0.40 secs] - Winter racing in very cold temperatures on wet, windy, sloppy tracks will often produce slower racetimes and overall favours the 'finishers'. The races being slower run than normal inevitably gives the 'stayers' more time to get into a virtual dog race!

Wet Track - [+0.20 secs] - A recent shower of rain generally makes a track run a little faster than normal, although persistent heavy rainfall invariably slows speeds down and overall tends to favours the 'outside runners'. The inside surface often becomes waterlogged due to the natural contours of a track, therefore dogs coursing a middle, wide and even sometimes an extremely wide raceline, frequently have the advantage of running on a faster surface!

One type of weather condition besides perhaps heavy snow or frozen ice that may occasionally lead to a meeting being abandoned is that of thick fog, as it will be deemed too dangerous to race, once the 'hare controller' has lost sight of the lure and its distance to the leading dog.

As all 'Predictors' will know, race conditions affect results and therefore play a vital role in understanding 'The Science of Greyhound Race Prediction'!

Now enter the track condition - Fast, Normal, Slow or Wet.

Greyhound Predictor v2.0 Track Dimensions

3 - Race Lengths

In this section, I mention the dog racing distances used here in the United Kingdom & Ireland and explain how standard prefixes identify each race distance. Please see British & Irish Greyhound Track Race Lengths

Greyhound Race Distances

Greyhound Predictor Software v2.0 lets you predict 3 race lengths: 515 metres = 563 yards, 500 metres = 547 yards and 480 metres = 525 yards. When studying the raceform, please select a race close to any of these distances to obtain the best predictions!

All race lengths can be displayed in metres or yards by choosing Options from the Main Menu. Alternatively, you can pre-set your own distance measurements by finding the Configuration Utility on your computer: (Start - Programs - Greyhound Predictor v2.0 - Configuration) as the default mode of your choice, each time you start up Greyhound Predictor only then will these race settings be saved for you!

In the United Kingdom there are basically four types of greyhound distance. A raceform prefix (abbreviated letter) is always shown before the 'grade' to represent the distance of race: D = sprint races (2 bend racing), A = middle-distance races (4 bends), S = stayers races (6 bends) and E = marathon or extended races (8 bends or more). Please note: In Ireland racing prefixes are slightly different ie: S = Sprint, A = Middle-Distance and D = Long Distance. Although 'prefixes' can vary from track to track!

By far the most common distance used for racing in England, Ireland and Scotland is 480 metres or 525 yards: The Arc - (Swindon), Gold Cup - (Monmore), All England Cup - (Newcastle), Grand National - (Central Park), Irish Oaks, Gold Cup - (Shelbourne Park), Kirby Memorial - (Limerick), Laurels - (Curraheen Park), Produce Stakes - (Clonmel), Scottish Derby - (Shawfield) are all run over this standard trip.

In February, Hove introduced the 2019 Coral Winter Derby a Category One competition to commemorate their new distance of 490 metres / 536 yards.

Colwick Park, Nottingham will host the 2019 English Greyhound Derby to be run over the new modern-day derby distance of 500 metres / 547 yards.

One of the oldest 'sprint classics' is the GRA Scurry Cup, first run at Clapton in 1928 over 400 yards until its closure in 1973. In 1974 it was switched to Slough over 434 metres / 475 yards and later in 1987 to Catford over 385 metres. In 2003/4 the race wasn't run until reinstated in 2005 at Perry Barr over 275 metres and in 2009 transferred to 'sister track' Belle Vue over 260 metres.

The Cesarewitch is another of the original classics, first staged in 1928 at West Ham over 600 yards, following that tracks closure the event transferred in 1972 to Belle Vue, Manchester over 880 yards, and was the first time a classic had ever been staged in the North of England. In 1995 the GRA switched the venue to Catford Stadium over 718 metres until in 2001 it moved to Oxford over 645 metres until it's closure in 2012. In the following years the race wasn't run until in 2019 Ladbrokes/Coral stepped in to sponsor the event and is now run at Crayford over 874 metres.

The St Leger was transferred in 2017 from its former home of 'Plough Lane' Wimbledon to its new home of Perry Barr in Birmingham and is now run over 710 metres. The longest marathon race in England is the Ladbrokes 1048 held at Crayford over 1048 metres!

In Ireland the 'premier sprint' is the Irish Sprint Cup run over 400 yards at Dundalk, which succeeded the National Sprint run over 325y at Newbridge.

The Irish Greyhound Derby held at Shelbourne Park, Dublin from 1932 has been run over 550 yards / 503 metres approximately since 1986. Interestingly, the Irish St Leger first held at Celtic Park, Belfast in 1932 is today staged at Limerick over the same distance of 550 yards!

Famous 'staying races' include the Corn Cuchulainn run over 750 yards, Night of Stars Marathon over 850 yards and Best Car Parks Marathon run over 1025 yards - (Shelbourne Park) and not to forget the historic "Ted Hegarty" Track Bookmakers Open Marathon previously staged at Harolds Cross. Although, perhaps the longest race in Ireland is the TBO Marathon held at Thurles over 1035 yards!

In the USA most parks display race distances as fractions of a mile: 990 feet = 3/16th mile, 1320 feet = Quarter mile, 1485 feet = Futurity course, 1650 feet = 5/16th mile, 1980 feet = 3/8th mile, 2310 feet = 7/16th mile, 2640 feet = half mile, 2970 feet = 9/16th mile, etc.

In Australia only two race categories are used: Sprint = all races up to and including 564 metres, and Distance = all races over 565 metres or further.

The positioning of the starting traps is very important as regular distances take place where runners are only afforded a 'short run' to the first corner. These contests frequently result in 1st bend trouble due to the distinct lack of 'racing room' and therefore will always be a little more difficult to predict!

The greyhound form statistic length of race? is found at the top of each race heading.

Now select and enter one of the three distances supplied.

You have now completed all the RACE-SET-UP questions and will be asked to answer a further set of seven questions by once again studying the raceform for each runner starting with trap one. Please select as before by highlighting any of the multiple choice answers and PRESS SPACEBAR to enter. Please note: race lengths, ages, weights and racetimes will require you to enter numerical answers by using the number digits situated on your keypad.

4 - Runner or Vacant

In this section, I discuss the maximum number of runners allowed in a race and the importance of the trap draw when predicting races around the world. Also mentioned are the greyhound racing colours used in the GP v2.0 Software Program.

Is this greyhound a runner?

Greyhound Predictor v2.0 allows you to simulate races that include vacant traps!

This feature lets you take out the non runners and create your own greyhound trial sessions - grade T = trial, T2 = 2 dog trial etc, solo trial = 'solo'. American Raceform = (st). Australian form 'pt' = private trial or 'qt' = qualifying trial. All combinations of a maximum 8 dogs are available.

In the United Kingdom and Ireland races are currently limited to six dogs. Although in the past eight dog races were once a regular feature. In Scotland, Shawfield still hold five dog races! In America and Australia the maximum number is eight, although nine and ten dog races have previously been held.

In English graded racing the 'trap draw' is allocated by the racing manager. All the inside runners will be issued with a 'rails tag' and will be seeded rails. An (R) written after a greyhound's name always indicates a railer. The first railer drawn out always occupies the first available inside trap position.

All middle trackers have the letter (M) after their name and will be given a 'middle tag' and seeded middle. Due to a change in the draw precedure, the first middle seed drawn out now occupies the first available position placed next to the nearest inside runner.

In UK greyhound form a (W) after a dog's name indicates a wide runner and is given a 'wide tag' and seeded wide. The first wide seed drawn out always occupies the outside trap position. Only extremely rarely when six wides are in a final or handicap race will a wide racer ever occupy the inside box.

The procedure for Open Race trap draws under the GBGB equal distribution rules, means that three seperate draws take place, with railers now known as unseeded runners drawn first, then middle seeds and lastly wide seeds. The first unseeded runner goes in the inside box of Heat 1, the second in the inside box of Heat 2 etc.

Open dogs when first trialed at a new track in preparation for a forthcoming competition may occasionally alter their natural racing line. The trainer may then decide to ask the 'racing manager' for a change to their dog's seeding position. This will only be granted when it is genuinely believed the dog would perform better if allowed to start future races from a different trap position. I believe the general reasoning behind this is based purely in the 'interests of safety' as overall seeding promotes cleaner trouble free greyhound racing and thus encourages dogs to perform to their maximum capabilities.

Alternatively in America, Australia and New Zealand there is no race seeding! any runner can be drawn in any box position, no preferences are given and therefore "the luck of the box draw" plays a leading role in determining results and is always an important factor to take into consideration!

I suggest when using the PREDICTOR that you first conduct your own private trials in order to see how different 'trap positions' affect performances. Please note: The option to trial dogs and then 'RACE AGAIN' is only fully functional in the Full Registered Version.

It is generally thought when betting on dogs, that any runner drawn next to a 'vacant trap' has a "good draw" as theoretically with more 'racing room' they've a better chance of starting well in the very early stages! Although, this always depends on the individual 'make-up' of each race!

Now enter Runner or Vacant.

Greyhound Racing Colours

Since world governing bodies have their own respective colour code of dog jackets, rugs or blankets, there can often be a confusion identifying the runners when watching on television or viewing via the Internet. This will exist until all greyhound jacket colours are perhaps one-day unified!

Here at Greyhound Predictor we found ourselves choosing our own greyhound colours and wishing to appeal to all 'fans worldwide' we decided that the following colours would hopefully be considered a fair choice:


Our reasons for selecting these colours were as follows: The first three traps: Red = T1, Blue = T2 and White = T3 just so happen to be the same colours used by the UK, Irish, European and American greyhound industries, and therefore the choice was simply made for us.

Choosing the next 3 colours was difficult, as each of the respective nations use different colours for each trap. After careful thought, we decided to stay with the GP v 1.0 colours and use the European, British and Irish greyhound colours: Black = T4, Orange = T5, and Black / White stripes = T6.

The task of choosing the colour of Trap 7 was again made difficult, as each of the 'dog racing nations' use different colours for this trap number. However, it was decided to represent the American greyhound industry and use the colour of Green and White Stripes = T7.

Lastly, it was decided Trap 8 should represent the Australian and New Zealand industries and therefore the famous Pink Jacket = T8.





5 - Dog or Bitch

In this section, I discuss the importance of the gender when predicting races and explain how to calculate the number of weeks out of season.

Is this runner a Dog or a Bitch?

Knowing whether a greyhound is male or female is very important as it indicates to the overall consistency of race performances. The majority of greyhound races around the world take place with both dogs and bitches competing against each other at various trips and distances.

Dogs generally are considered more consistent and thought best suited to sprint and middle-distances. There are always exceptions to the rule!

Bitches on the other hand are much harder to train, as race schedules are continuely interrupted when a bitch goes into season (Ssn) and will usually be withdrawn from all her racing activities for at least 21 days under GBGB Rule 56 or until the track veterinary surgeon is satisfied she's fit to race. Although, usually they can be 'off the track' for at least 8 - 10 weeks.

Once a bitch is retired to the paddock and put to a stud dog for breeding she becomes a 'brood' and will be called a 'dam' after whelping her first litter. When studying form all 'race-goers' will pay particular attention to the 'breeding lines' of all competing greyhounds and should always note when a former 'top class' racing bitch has produced offspring to a 'classic winning sire'. Although, there can never be any guarantees when it comes to breeding, these litters are said to be "bred in the purple" with famous pedigrees. These much sought after 'young sablings' may share similar colourings and markings and show 'racing traits' common to either their sire or dam - racing styles, distances etc.

In UK greyhound form books: d = Dog and b = Bitch and is located left of the sires name and preceded by other abbreviated letters referring to its colour: bk. d. = black dog, = white brindle bitch, f.w.b. = fawn white bitch, be.d. = blue dog etc.

In American racing form stats (m) = male dog and (f) = female dog.

Now check your newspaper and enter Dog or Bitch.

If you have selected Bitch the following question will be asked:

Is the Seasonal Date = Known, Not Known or Suppressed?

Knowing the season date gives a clue to their general level of fitness. Most bitches returning from a seasonal rest will be 'race rusty' and perhaps due to the lactose - sugary substance contained in milk - build up in their systems, may be carrying a little extra weight. After a few trials and races these 'seasoned bitches' will begin to show signs of returning to peak form - change in running style, faster sectionals, improvement in racetimes etc.

It is generally considered the "perfect-time" for a 'greyhound bitch' to be approaching peak fitness is 16 weeks out of season. Although some win races sooner perhaps at 14 weeks, while others may indeed be slower 'coming to hand' and take longer to find 'top form', perhaps 18-24 weeks.

Please note: when 'female dogs' start to show better form, they often consistently run well and may continue to improve, as overall they follow their own natural cycle of either 'coming into form' or 'going out of form'. As the old greyhound adage says "It always pays to follow a bitch in form!"

Now check the formlines again.

The seasonal date is found next to the 'whelping date' eg: May 15 (Season 04 Apr 17)

Occasionally a heavily raced bitch may be irregular in her seasonal dates, which may result in two or even three seasons occurring in any one year. Although one of these maybe a 'false heat' where no results would come from breeding and some don't have a season at all!

Season Unknown - If No Seasonal Date (nsd) appears in the racing form, then select Not Known.

Season Suppressed - Greyhound trainers may sometimes administer 'suppressants' to certain bitches in order to delay or stop a season from occurring. This allows them to continue racing 'on the track' rather then being sidelined for many weeks 'off the track' due to an enforced seasonal rest.

If the raceform abbreviation (Ssn Sup) is shown or if a bitch has been 'spayed', then select Suppressed.

Seasonal Date Known - If you have selected Known? - The following question will be asked:

How many weeks out of season?

To answer this question simply calculate the approximate number of weeks that have elapsed since the last seasonal date occurred!

Alternatively, If you decide she's running well, then simply enter 16 weeks out of season! GREYHOUND PREDICTOR v2.0 will then simulate her best form. Or if she's not running well, simply leave the seasonal weeks blank! The PREDICTOR will then simulate her running 'below par' or being 'out of form'.

Now enter the number of weeks.

6 - Greyhound Ages

In this section, I explain how a dog's racing age may affect its track performance and provide a link to Greyhound Welfare and Dog Re-homing sites.

What's this Greyhound's Age in Months?

Knowing the runners age is a very important factor when predicting canine races, as it implies to the general consistency of performances.

Greyhound Predictor v2.0 Software requires all ages of dogs to be entered in months!

In UK Racing Form, the age of a dog is always taken from the first day of the month, even if born on the last day of the month!

All greyhounds less than 24 months old are classified as puppies and will at approximately 12 months old be introduced to the idea of racing, after initial schooling trials most juvenile dogs that achieve a 'grading in time' will make their race debuts between 15 - 18 months of age.

Some trainers may elect to bring certain 'well bred pups' on slowly at first, deliberately keep them back, wrap them in cotton wool perhaps and then introduce them fresh in the spring from a winter's break, in order to get them fully fit for the 'Puppy Opens' held later in the summer months.

These raw lightly raced greyhounds are open to much improvement over the following weeks and months, as they possess good racing potential, which is always considered a good sign when predicting future race winners! However, 'greyhound pups' frequently run a little 'green' and race inconsistently, as obviously young puppies are still learning to win dog races.

The age at which a greyhound reaches it's prime can vary enormously. It's generally thought that a dog's best age is between 30 - 36 months, although I believe some may peak much earlier between 21 - 30 months and consider this to be the perfect age for backing dogs running over sprints and middle-distances. Although bitches may take a little longer to reach their full potential.

More experienced dogs between 36 - 48 months old will be competing in their second or third racing season. These dogs are much more battle hardened to the hustle and bustle of regular racing and remarkably produce very consistent performances, illustrated by the close proximity of their recorded times.

Open class 'Marathon bitches' it is said often improve their performances in their second season of racing over these extended distances!

All veterans over 48 months old will be approaching the twilight of their careers and many will sadly be retired. However, there's always exceptions to the rule, as a few 'seasoned campaigners' will continue winning races, although most will lack that bit of spark or back-straight pace they once possessed!

The lifespan of a greyhound is varied. The legendary Mick The Miller lived to the age of thirteen years old. Although, bitches may live a little longer, many up to fourteen or fifteen and have also heard of greyhounds living to twenty!

Greyhound Predictor now has an extra page dedicated to greyhound rescue sites if you can in anyway help in the re-homing of retired ex-racing dogs, please visit our greyhound welfare page.

Now check your newspaper.

To know how old a greyhound is? you will need to find the 'whelping date' which is usually located in the race formlines to the right of the dam's name. Then simply calculate the approximate number of months that have elapsed since the whelping date occurred!

Now enter the age in months.

7 - Greyhound Racing Weights

In this section, I explain how variations in weight may affect a dog's performances and give my reasons for collecting greyhound programmes.

What's this Greyhound's Weight?

Greyhound Predictor requires all race-weights to be entered in either Kilos (Kgs) or Pounds (Lbs). All weight conditions can be simulated!

All United Kingdom, European, Australian and New Zealand greyhounds are weighed in Kilograms. American and Irish dogs in pounds.

Dogs weigh on average between 28 - 36 Kilos = 62 - 80 Lbs. and stand 71-76 cms tall. They are generally considered fearless when racing and show great determination and bravery to the vast pleasure of their connections and the crowds that watch.

However, a few male racing dogs consistently find trouble in races and may be considered a little awkward or clumbsy! Some of these 'long striding dogs' can weigh in excess of 40kg = 88lbs and are perhaps better suited to racing on wider galloping tracks with much bigger circumferences. Although, they do have an advantage over bitches when conditions underfoot become wet or sloppy as they take less strides to run a circuit!

Bitches weigh on average between 22 - 31 Kilos = 48 - 68 Lbs. and stand approximately 68 - 71 cms tall. They protect and look after themselves a little more then dogs and often display 'good trackcraft', as they can squeeze through racing gaps that larger dogs wouldn't dare to go and also have the advantage of sometimes being able to 'slip under the grill' a little quicker then dogs, when initially breaking from the traps!

All runners and reserves for races are put on the scales and kennelled prior to racing. Australian and British Racing dogs that have a weight variation above or below 1kg or 2.2 Lbs (American racing 2 Lbs) from it's previous weight will not be permitted to run under normal racing rules!

Knowing the racing weight of a greyhound is extremely important as it allows you to determine a dog's true race condition. However, finding out the weights may prove difficult, as presently the only way of knowing is to visit your local track!

I suggest, that the 2nd thing you should always do while attending a meeting, is to check the 'weight sheet' displayed at your local greyhound stadium or park! This is a big advantage in selecting winners and a major reason why so many people love going to the dogs!

Future advancements in technology may afford 'off track punters' with this weight information. Although, many of us will simply not know a dog's previous weights in order to compare them. Although a few of us 'anoraks' will simply refer back to their more recent old programmes!

If the weight of a greyhound isn't known, simply enter your own approximate weight or alternatively you can leave the race weights blank = 00.0 kilos or Lbs. The 'Predictor' will then set this runner a normal racing weight!

Now enter the weight in kilos or Lbs.

What's this greyhound's weight condition?

All greyhounds have their 'perfect weight' known only perhaps to the trainer and maybe the owners! When a dog weighs close to their optimum weight, this implies their fully tuned up and ready to produce their top performances. This is best observed by studying weight variations from race to race!

Under Weight

Any greyhound racing 'down in weight' is generally a good positive sign! As losing weight suggests they will be fitter having been well exercised. Personally, I believe they produce slower than normal sectionals, but compensate by having a little more stamina at the end of a race.

Some greyhounds when kennelled before racing will be prone to 'kennel fretting' and become nervous or over excited and may lose weight rapidly before finally being placed into the starting traps. This is alternatively considered a negative sign! as it suggests perhaps a weakness in the racing temperament of the dog, which often results in greyhounds running inconsistently - missed breaks, early faders etc.

Any puppies running with an under-weight racing condition is sometimes also considered a negative sign!

Normal Weight

When there is little or no difference between current or previous weights, then select 'normal weight condition'. This is always seen as a good sign! as the consistency of weight always indicates to the general well being of the dog!

However, any dog previously thought 'down in weight' and was racing again, should still perhaps be considered 'under weight' even though it's weight remains the same! Just as a dog running 'over weight' and remaining at that weight for it's next race, may still be considered 'up in weight'!

Over Weight

Most "canines" returning from a 'lay off' maybe over-weight, which is always thought a negative sign! as it suggests they've been overfed or not exercised enough. Personally, I consider these dogs to be initially stronger and genuinely believe 'up in weight' dogs produce fractionally faster than normal sectionals. Although overall, they 'tend to fade' a little sooner then they would normally do in the latter stages of a race!

Handlers I believe, may occasionally elect to put weight on a greyhound in order to help a dog trap out faster, giving them perhaps a better chance to lead up or lie handy with the pace in order to avoid possible trouble anticipated at the corner!

Any pups up in weight is alternatively considered a good sign! as it suggests they're still growing and therefore open to improvement!

Dogs weight condition = Not Known

If as is generally the case a dog's racing condition is unknown then simply select Not Known.

Knowing the weight condition is only afforded to 'trackside punters' who simply compare the differences in weight if any, against previous weights displayed in their racecards. When weighing up the form of a race, the one vital factor, besides the times, the age, the going and the draw, that allows me to determine which dogs to include in bets, should in theory always be decided by the greyhounds with the best weight condition!

However, dog racing weights can be very misleading! lets imagine that Lady Flyaway has a perfect weight = 27.0 kg and having competed in her last race at a weight = 28.0 kg, we find that the Lady's running tonight at a weight = 27.6 kg. Would you consider her to be under weight or perhaps over weight?. Here lies the general confusion as to why weights are so often misunderstood! In the above example, Lady Flyaway weighing 27.6 kg is in fact 0.6 kg over weight, as we knew her best weight = 27.0 kg. Although, had we thought her ideal weight = 28.0 kg then I would consider her 0.4 kg under weight!

"Punters" will appreciate, that dogs 'up in weight' can still be 'under weight' and dogs 'down in weight' can still be 'over weight'! Most of us already know dogs are heavier then bitches, although knowing the exact weight, is of little use, unless you're able to compare these 'weight differences' to determine a dog's true weight condition.

This ability to study greyhound weights, combined with an accurate estimation of their 'optimum weight' is vitally important, as any change in racing weight affects performances and therefore plays a significant role in obtaining accurate predictions!

It is only by collecting these official programmes can the serious "racing student" study the 'weight variations' displayed further back in past greyhound formlines and is perhaps why so many of us like to collect dog programmes? Please don't throw them away!! So many collections of memorabilia go to waste! If you happen to find any old racing programmes and your thinking of throwing them out, PLEASE DON'T, instead contact me. All names of contributors to my collection will be mentioned!

Now enter weight condition - Under, Normal, Over or Not-Known.

8 - Greyhound Race Times

In this section, I explain how to enter the fastest/average race and sectional times into the Greyhound Predictor Stat Screen. For general racing times, Please see British and Irish Greyhound Track Records and Dates.

Best Recent Time?

Greyhound Predictor 2.0 requires a greyhound's fastest time to be entered. All 'middle-distance' races can be simulated!

Knowing a dog's quickest time is extremely important as it indicates to their top racing performance, which in turn implies to the 'class of the runner' and also allows us to calculate the average speed of a greyhound racing around a track. Please 'visit the past' and download GP Version 1.0

Since stadiums around the world have varying track dimensions, I would like to point out that all winning times achieved on circuits with 'smaller circumferences' may not truely represent a dog's racing ability, as speeds associated with 'sharper tracks' always produce slower times!

I suggest when entering times into the 'Predictor' that you always feel free to 'add on or deduct' an appropriate amount of time, in order to bring these timings into line with the Greyhound Predictor Track. To find the time to be adjusted, you must first trial individual dogs with different times recorded over different distances at tracks with different circumferences and surface conditions, then decide how these winning-times compare and adjust accordingly, as we say "It's not a Game? It's a Science!"

However, greyhound racing times can be very misleading! For instance, if a dogs raced only once, then its obviously 'open to improvement' and will in future races no doubt achieve better times. Whereas a dog racing many times over the same distance may invariably struggle to reproduce their best times. Alternatively a dog returning to the track after a short rest, spell of lameness will also struggle to reproduce their quickest times. Please note: since the fastest time is shown in Uk racecards within the last 3 months, some dogs may have previously clocked a quicker time, although this fastest ever or lifetime best time is not currently displayed in trackside raceform.

If a greyhound has No Best Time (NBT) displayed in the formlines, then this dog has yet to race or trial over the trip. Therefore, you may need to enter an alternative time taken from one of it's previous races, run perhaps over another distance or achieved on a different track or alternatively you can always enter your own pre-adjusted racetime in order to best simulate a greyhound's real performance.

In United Kingdom dog form books the winning time (Win/Tm) is located to the right of the race remarks. However please note, that all recorded times are then adjusted accordingly after the race to take into account the condition of the racetrack. These are known as the 'calculated racetimes' (Calc/Time). An asterix (*) shown after one of these times always indicates a dog's best recent time. When choosing to enter an 'amended time' please make sure a greyhound's obtained a clear run or a good finishing position in order to enter a time that best reflects its true racing capability.

Is it a Game?

GP v2.0 allows abnormally fast or slow racetimes to be entered! allowing you to simulate slightly shorter or longer middle-distance races with more variations in sectional timings and wider winning race margins! but more importantly lets you further enjoy the fun element to Greyhound Predictor! Please see Betting Lounge!

Watching the dogs race in real-time is the key to a successful prediction and makes GREYHOUND PREDICTOR a unique tipping tool and Game!

Now check the formlines.

The Best Time (BT) or Best Recent Time (BRT) is located directly below each dogs breeding lines.

Now enter the fastest time.

Best Sectional Times?

Greyhound Predictor v2.0 allows all middle-distance sectionals to be entered!

A 'sectional' is the time it takes for a dog to run from the starting traps to the winning line first time around the circuit. This is important to know as it will provide a clue to a dog's pace-type, early race position and also lets us calculate the acceleration speeds of a greyhound exiting the traps!

In American race-cards this is known as the 'first turn time' (FTT) and shows the leading dogs time to the escape turn.

Since most tracks have different circumferences and 'run-up' (RnUp) distances from the boxes, I suggest if your 'split times' are not relevant, then again, please feel free to 'add or subtract' an appropriate amount of time, in order to bring these timings into line with the Greyhound Predictor Track Times.

I suggest using the slightly longer 515 metre track to better simulate the precise distances between the dogs in the very early stages of a race!

Now check the formlines.

All 'sectional timings' are located directly below each greyhound's name and are preceded by the race distance and the previously occupied box or post position, for instance, 515 [1] 04.30 = (This dog ran over 515 metres / yards, from trap no.1 and recorded a sectional time = 04.30 secs.)

If 'no sectionals' are stated, leave your answer blank = 00.00 secs. The 'Predictor' will then set this dog an average sectional based on its pace-type!

Now enter the best sectional time.

Understanding Breaking Times

Greyhound Predictor lets you simulate missed breaks! As a general rule in determining short distances: 0.08 secs = 1 length, 0.04 secs = 1/2 length, 0.03 secs = a neck, 0.02 secs = head and 0.01 secs = short head. Although the actual time it takes a dog to run a length may be fractionally quicker 0.0676 secs = 1 length. Therefore, dependent on you viewpoint, if you wished to simulate a dog missing it's break by two lengths for example, then simply multiply 2 x 0.08 = 0.16 and add this time to it's best sectional time, eg: 04.30 secs + 00.16 secs = 04.46 secs or alternatively use the slightly faster sectional length timing, eg: 04.30secs + 00.13 = 04.43 secs approximately, again the choice is yours!

At British tracks with mainly six or eight runners in a race, the hare travels past the starting traps at approximately 35 mph / 56.33 kph! The widest trap position is always the closest runner to an 'outside hare' and theoretically has the advantage of seeing the hare go past first! On the other hand Trap One being further away, is theoretically always the last dog to see the lure. Therefore, for these reasons early paced wide running greyhounds invariably break fast from an outside trap position but generally don't trap so well when placed in the 'coffin boxes' or 'middle traps'!

Alternatively, dogs previously raced from an inside position invariably improve their breaking times when drawn further out in the middle of the track, as theoretically they see the hare fractionally sooner being drawn nearer to it. While greyhounds producing fast trapping times from the middle boxes often struggle to reproduce the same sectionals when drawn closer to the inside fence, as they see the lure fractionally later.

In America, Australia and New Zealand predicting breaking speeds is interestingly the opposite way around! as the greyhound closest to an 'inside hare' at 'trap release' is Trap 1, which theoretically always has the advantage of being the first dog to see the lure go past. While Trap 8 being furthest away is theoretically the last to see the lure. Since GP v2.0 dogs follow an outside hare, I suggest you may need to quicken up the times of the inside runners in order to better simulate dogs chasing an inside lure!

Understanding why a dogs sectional time may alter due to its starting position is vitally important, as these fractional hundreths of a second differences in break times not only set the initial pattern to a race, but influences any 'race interference' that may take place!

Occasionally an early paced runner will momentarily be "left in the boxes" and in its eagerness to rejoin the race leaders, may accidently cause crowding (crd), baulking (blk), bumping (bmp) or bunching (bnc) around the opening turns, all initially caused by the mistiming of a greyhound's break!

All Dogs in the Predictor have their own hit detection and can simulate: Crowding = +0.10secs, Bumping = +0.20secs and Baulking = +0.30secs!

Distance of Best Recent Time?

I suggest first trialing dogs to fully understand how small changes in distance can simulate different grades and affect the times in the Predictor.

By using GP's 515 metre / 563 yard track, it's now possible to simulate Irish 525 - 550 - 575 yards and American 5/16 of a mile races!

Technically, when using Greyhound Predictor you should always choose the closest race length to the distance your predicting and indeed you can. However, instead of entering the race distance as ie 550 yards = 503 metres, I suggest you add 13 yards or 12 metres and enter 563 yards or 515 metres. As this distance will not only simulate breaking times with an American style 'longer run' to the first bend, but will also take into account that the Greyhound Predictor Track generally runs a little faster then an 'average sized track' due to it's own scale specifications, ie: bigger circumference. Therefore, all racetimes entered remain extremely relevant to the winning times recorded over this slightly longer distance!

Now check the formlines.

All previous lengths of races are preceded by the 'race dates', eg: 04 Aug 515 = 515 Metres or Yards.

Now enter the race distance.

Average Race Time?

To enter the average time of a greyhound you simply calculate the approximate average of all the racetimes relative to the distance your predicting. When calculating averages you may wish to ignore significantly slower times due to a dog being knocked over (ko), fell or did not finish (dnf).

In order to quicken up data entry the 'Predictor' allows average times and distances to be left blank!

Please be aware of mis-prints, hand timings (HT or Hnd Tm) and races run over the same distance but in fact recorded on another track!

Now enter the average racetime.

Average Sectional Time?

To calculate the average sectional simply look at previous runs over this distance and enter your estimate of the 'average breaking time'!

If No sectional time is displayed in the raceform, then you may need to enter your own estimate based on previous sectionals achieved over different race lengths or alternatively recorded on other tracks with different run-up distances or simply leave it blank!

Now enter the average sectional time.

Distance of Art?

GP v2.0 uses the abbreviation A.R.T. which stands for Average Race Time.

Now enter the race distance.

9 - Greyhound Pace

In this section, I explain how to determine the racing pace of a greyhound and discuss the advantages and disadvantages of individual racing styles. Studying Sectional Timings, Reading Race Comments, Observing Track Positions and American Chart Writers are included.

Type of Pace?

Greyhound Predictor Software Version 2.0 allows for four types of racing pace to be simulated:

All dogs will have their own individual style of racing, this is best illustrated by observing a greyhound's pace in a race!

Early Pace - This type of greyhound pace produces very quick sectional times as these dogs reach their top speeds in the very early stages of a race. These "fast breakers" perform best when allowed to lead "on the bunny" from the start and rely on a clear run in-order to set an unassailable lead! Although, early paced greyhounds inevitably tire and may fade dramatically in the closing stages!

Middle Pace - Dogs with this running style are seen to their very best effect when accelerating along the backstraights in the middle-stages of a race. Although, they often find themselves racing closely surrounded by other dogs in a tightly packed field and for this reason are more prone to interference then other pace types and maybe impeded or forced to check when challenging at the 1st or 3rd bends!

Finishing Pace - All 'staying dogs' show their best running when gaining ground towards the end of a race and subsequently benefit when trouble occurs amongst the pace-setters. Although, 'finishers' will have to pass all the other dogs in-front of them and can be frequently hampered or forced to run wide! Most 'puppies' finishing fast in races will in time be stepped up in distance, as will most dogs better suited to longer races.

All Round Pace - These hounds maintain a 'strong gallop' throughout a race. Although, sometimes this may be considered a little one paced!

Now check your raceform.

To know a dog's pace type, you must literally read between the race formlines, as there is no specific statistic or racing data that will inform this. However, clues are given and basically there are three ways to calculate a greyhound's pace:

1 - Studying Sectional Times - You should always try to compare 'sectional times' run on the same date and over the same track distance as this will generally inform you which greyhounds are fast, average or slow away in the first few seconds of a race.

In Australia, some of the world's finest stadiums or "city tracks" sometimes supply 3 split times: the initial run to the 1st bend, the approximate 1/2 way clockings and 'coming home' or 'home run' sectional measured to a 1000/second from the top of the back-stretch to the winning line maybe stated.

2 - Reading Race Remarks - The following comments indicate pace-type:

Early Pace = (ep), clear 1st, led 1, very quick away (v qaw), fast away (f aw) always led (aled), led to line, box to wire.

Middle Pace = led 1-2 to run-in, led 2, led 3, slow away-early pace (sa ep), mid-stretch drive.

Finishing Pace = very slow away (vsa), lacked early pace (lep), led 4, led on line (ld ln), ran on (rn on), finished well (fw), stretch drive.

All Round Pace = These greyhounds share similar comments to other pace types and can win races by both leading all the way from the start or by staying on strongly at the end and perhaps overall perform best when holding a good early position!

In Irish greyhound race comments they use the term evenly away (ev aw).

3 - Observing the Race Positions - In UK racing formlines, all previous race positions are recorded at the 1st, 2nd, 3rd, 4th bend and finishing line. This data is located next to the 'sectionals' and usually provides an accurate guide to a dogs pace type:

eg: Early Pace = 1 1 1 1 2 - Middle Pace = 3 2 1 1 2 - Finishing Pace = 6 6 4 3 2 - All Round Pace = 2 2 2 2 2

Generally, it's easy to pick out the 'early pace' and 'finishers', although dogs with 'middle' or 'all round pace' will always be a little more difficult!

In America it's the 'official chart writers' who determine a runners position in a race:

Off Call or Break Call - This is the racing positions of the greyhounds 1-8 exiting the starting boxes.

The 1/8 Call - This is the dogs position exiting the 1st (escape) turn.

Stretch Call - This is the runners position in the field, measured at a point just entering the final turn.

Finish Call - This is the dog's final finishing position 1-8 measured at the finish line.

I suggest the 3rd thing to do while at a meeting, is to go "out for a shout" and take a look at the runners on parade. I like to see 'alert dogs' with their tail tucked well underneath themselves, resembling a coiled spring! rather than a 'sluggish looking' or 'happy dog' with it's tail waggling in the air!

I suggest the 4th and last thing all 'Greyhound Predictors' should remember when going to the "bow wows" or "cherryhogs" is to continue watching the dogs run to the 'pick up' or 'sough' (sgh) after the race finishes, as this will help identify the correct racing pace for all your future predictions!

Now enter Early, Middle, Finishing or All Round Pace.

10 - Racing Lines

In this section, I explain how a dog's racing line affects its performance and discuss the advantages and disadvantages of different running routes.

Greyhound Racing Lines

Greyhound Predictor v2.0 offers an amazing 16,384 individual race-lines! You can select a Standard Racing Line or Define Your Own.

All combinations of the following track positions can be simulated:

Rails - Greyhounds racing on the inside are known as 'railers' and always have the distinct advantage of running the shortest route around a circuit. Holding the rails position is extremely important as these "paint scrapers" frequently avoid trouble in a race by slipping through along this inner fence and hence benefit when other dogs are crowded or baulked to their outside. However, they can also be blocked behind a wall of dogs and may not always maintain their fastest speeds around the bends due to the acuteness of this particular running line!

Middle - All 'middle-trackers' are better placed to maintain their maximum speeds throughout a race. Although they run a little further compared to railers and are often considered 'easy to pass' as they allow chasing dogs plenty of room to overtake them both on the inside or outside of the track!

Wide - Dogs running wide are usually favoured by wet racing conditions and will inevitably benefit in races when trouble involves the inside dogs. However, 'wide runners' run further in distance compared to 'inside' and 'middle-runners' and generally lose a little ground around the bends!

Very Wide - Some greyhounds naturally run very wide! This is always thought an 'inferior racing-line' as they obviously lose many lengths around the corners and run much further in distance. However, very wide runners are also favoured by wet track conditions and nearly always avoid other runners by taking this extremely wide route, although occasionally they do end up racing on the wrong side of an outside hare rail!

All greyhounds chasing artificial hares will choose their own natural running paths depending on whether their following an inside or an outside hare? In America, Australia and New Zealand an inside lure is generally used and therefore the dogs run much closer to the rails.

Alternatively in the United Kingdom and Ireland races take place behind an outside hare and therefore dogs tend to run more in the middle to wide areas. This is most noticeable watching greyhounds racing out of the turns and running along the straights!

Now check the race comments.

In English racing: Rails = rls, Rails to Middle = rls-mid, Middle to Rails = mid-rls, Middle = mid, Middle to Wide = mid-w, Wide = w, Very Wide = vw.

Now enter Standard Racing Line or Define Own.

If you select a Standard Line the default racing line for each trap or post position will be highlighted on the Track Screen.

If you select to Define Your Own you may choose any combination of racing lines for each of the GP v2.0 Track Positions:

You've now completed all the data for Trap 1. If you've made any mistakes the 'Predictor' will let you go back and alter any race stat.

Now highlight Enter and Press Spacebar to load the dog into the traps.

Once you've repeated this procedure for all the remaining runners, you will start to see the GREYHOUND PREDICTOR TRACK!

Race and Final Conclusion

In this section, I explain how to best view Greyhound Predictor Software and discuss the general probabilities involved in greyhound race prediction.

The Race

Greyhound Predictor Version 2.0 lets you pre-study future dog races in the comfort of your home!

Once the GP v2.0 Racetrack has loaded, you can select the Display Mode by using either the left / right cursor keys situated on your computer keypad. This 'special feature' shows the 'racing speeds' of the dogs in metres or yards per second or miles or kilometres per hour and the distances travelled!

Press Spacebar to start the hare running As soon as the 'traps open' the RACE PREDICTOR will continuously up-date each dog's race position!

Press Spacebar to pause the action This feature allows you to 'stop the race' at any time in order to examine the future possibility of any crowding, bumping or baulking occuring anywhere around the circuit. Please note: By repressing the Spacebar the race continues from the exact moment it was paused and that all win times and predictions are not affected by pausing then re-starting a race.

The Official Result will show the winning time, fastest sectional time, race length, track conditions and final finishing positions!

Select Photo by pressing the left / right cursor keys you can see the actual photo finish as the first greyhound crosses the line.

Select Race Again Please note: *This limited game feature is only fully functionable in the full registered version

Registering Greyhound Predictor not only lets you re-run the race with all the 'stats' saved for you, but alter quickly any data needing to be changed! Each race set-up I suggest, should be run several times in order to gain the necessary insight required to make a successful prediction!

The Science of Greyhound Racing Prediction - Final Conclusion

It is with immense gratitude to my own family and friends, and the many people who over the years shared their greyhound knowledge with me, that I'm now able to express my own original ideas and general observations in attempting to fully comprehend the complexities involved when studying race prediction.

We are often asked as to the accuracy of Greyhound Predictor? However, since each 'Predictor' will have their own independent strike rate of winners, no win ratios or win percentages are stated. Although, I should in fairness explain the general probabilities involved when betting on races:

Predicting winners theoretically will always be easier in 'six dog racing nations' such as United Kingdom, Irish and European racing where the probability is 1 in 6 compared to 'eight dog racing' as seen in Asia, Australia, New Zealand and North & South America, where the probability is 1 in 8.

Predicting forecast bets (f/c) or exactas 1st and 2nd in 6 dog races has a probability of 1 in 30 (6 x 5) compared to 1 in 56 (8 x 7) in eight dog races.

Predicting straight tricast bets (t/c) in six runner races has a probability of 1 in 120 (6 x 5 x 4), compared to eight dog trifectas where it's 1 in 336 (8 x 7 x 6).

Predicting superfecta bets - first four in order - is only operational in American 8 dog tote pool races and has a probability of 1 in 1680 (8 x 7 x 6 x 5).

All 'Players' will appreciate that these 'underlying probabilities' always exist when betting on greyhounds.

Since it's generally thought a greyhound's fastest time is the most important form statistic, then I suggest your attention is focused on this race-time data, as overall the accuracy of the PREDICTOR will almost certainly depend on the relative accuracy of the information entered!
