Glossary of UK Greyhound Racing Terms: Every Word a Sheffield Punter Needs

This greyhound racing glossary covers the terminology you will encounter when following Sheffield greyhound racing — on racecards, in results, in commentary and in the betting market. Some of these terms are shared with horse racing; many are specific to greyhound racing and have no equivalent elsewhere. If you have ever looked at a racecard and wondered what a form figure means, what a CSF is, or why the commentator keeps mentioning the “going,” this is where those questions get answered.

The entries are grouped alphabetically in three sections and written in the context of Sheffield racing at Owlerton, with practical examples where they help clarify the definition.

A–F: From Ante-Post to Forecast

Ante-post — a bet placed well in advance of an event, before the final runners are confirmed. In greyhound racing, ante-post betting is most common on major competitions like the Steel City Cup or the English Greyhound Derby, where markets open weeks before the final.

BAGS — Bookmakers’ Afternoon Greyhound Service. The commercial system through which bookmakers contract with tracks to provide racing content for their shops and online platforms. The majority of Sheffield’s 260-plus annual meetings are BAGS fixtures.

BSP — Betfair Starting Price. The price calculated by the Betfair exchange at the moment the traps open, based on unmatched orders in the market. Distinct from the traditional SP and sometimes offering different value.

Bumped — interference during a race where one dog makes physical contact with another, usually on a bend. Indicated by “b” in form comments. A dog that was bumped at the first bend may have finished poorly through no fault of its own.

Checked — a dog forced to slow down or change direction due to another runner’s movement. More severe than bumping. Indicated by “ck” in form figures. Always relevant when assessing whether a poor result reflects true ability.

Circumference — the total distance around the racing track. Sheffield’s circuit measures 425 metres, which places it in the mid-range of GBGB venues and contributes to the track’s distinctive tight bends.

Combination tricast — a tricast bet covering all possible orderings of three selected dogs in the first three positions. Costs six times the unit stake. Offers more flexibility than a straight tricast at higher cost.

CSF — Computer Straight Forecast. The industry-standard algorithm used to calculate forecast dividends after a race. The CSF takes the starting prices of all runners and generates a dividend for each possible first-and-second combination.

CT — Computer Tricast. The equivalent algorithm for tricast dividends, extending the calculation to the first three positions.

Form figures — a sequence of numbers on the racecard showing a dog’s finishing positions in its most recent races. Read left to right with the oldest result first. A form line of 2-1-3-4 means the dog finished second, first, third and fourth in its last four outings.

Forecast — a bet requiring you to predict the first and second-placed dogs. A straight forecast requires the exact order; a reverse forecast covers both possible orderings. Dividends are calculated by the CSF algorithm. In a six-runner field, the theoretical baseline probability of any random trap in a race is 16.6 per cent, making a straight forecast a genuinely challenging prediction.

G–P: Going Report to Puppy Race

GBGB — Greyhound Board of Great Britain. The governing body of licensed greyhound racing in Britain. Responsible for regulation, welfare, grading and the licensing of tracks, trainers and officials.

Going report — a description of the track surface conditions before a meeting. Sheffield’s sand track is affected by weather: rain makes it heavier and slower, frost can make it dangerous, dry heat makes it faster. The going influences race times and can shift trap bias. At Owlerton, with its 425-metre circumference, even modest changes in surface condition are amplified over four bends at standard distances.

Grade — the classification assigned to a dog based on its recent performance at a specific track. Grades range from Open (unrestricted) through A1 (highest graded tier) down through A2, A3 and so on. Dogs move between grades based on their results. A dog’s grade at one track is independent of its grade at another.

GRS — Greyhound Retirement Scheme. The GBGB welfare mechanism that requires a bond for every registered racing greyhound. The bond funds the dog’s transition into retirement through accredited rehoming centres.

Hare — the mechanical lure that greyhounds chase around the track. Owlerton uses an Outside Swaffham hare, which runs on a rail around the outside of the circuit. The hare type and speed can affect race pace and running style.

Middle runner — a dog that races in the middle of the pack through the early stages, neither leading nor trailing. Indicated by “m” in form comments. Middle-running dogs avoid the risks of leading (pressure) and trailing (traffic) but may lack the early pace to dominate at sprint distances.

Nap — a tipster’s best bet of the day. The term comes from the card game Napoleon and signifies the selection the tipster is most confident about. A Sheffield nap is the tipster’s strongest Owlerton selection on a given card.

Open race — a race with no grading restrictions, open to dogs of any grade. Open races attract higher-quality fields than graded events and are where feature competitions like the Steel City Cup are staged.

Overround — the bookmaker’s built-in profit margin, expressed as the percentage by which the total implied probabilities of all runners exceed 100 per cent. A lower overround means better value for the punter.

Puppy race — a race restricted to dogs under a certain age, typically two years old. Puppy races serve as the entry point into the graded system and are significant for identifying emerging talent.

Q–Z: Racecard to Wide Runner

Racecard — the printed or digital document listing every runner in every race at a meeting, along with form, trap draw, trainer, breeding and other data. The racecard is the primary research tool for greyhound punters.

Regrading — the process by which a racing manager moves a dog up or down the grading system based on recent results. A dog winning consistently will be raised; one finishing poorly will be dropped. Regrading happens on a rolling basis and is one of the most important signals on the racecard.

RPGTV — Racing Post Greyhound TV. A free-to-air television channel dedicated to live coverage of British greyhound racing, including regular Sheffield meetings. Available on Freeview, Sky and via online streaming.

Run-up — the distance from the starting traps to the first bend. At Sheffield this distance is approximately 62 metres, a measurement that significantly influences trap bias and the importance of early pace at different distances.

Sectional time — the time taken by a dog to cover a specific portion of the race, measured between fixed points on the track. Sectionals reveal pace patterns that the overall finishing time conceals — a dog with the fastest final sectional but a slow overall time was probably impeded earlier in the race.

SIS — Satellite Information Services. The dominant content supplier for greyhound racing in UK betting shops. SIS feeds deliver live pictures, pricing data and results from tracks including Sheffield to bookmaker premises nationwide.

SP — Starting Price. The official odds at the time the traps open, compiled by an on-course SP reporter from the prices offered by bookmakers present at the track. The SP is the default price for bets placed “at starting price.”

Tote — the pool betting system operated at greyhound tracks. Tote dividends are calculated from the total pool of money wagered on each race, minus the operator’s deduction, shared among winning ticket holders. Returns vary depending on how much money is in the pool and how it is distributed.

Trap draw — the starting position assigned to each dog, numbered 1 (red, innermost) to 6 (black, outermost). At Sheffield, the trap draw influences outcomes at every distance, with inside traps holding a statistical advantage at sprints due to the shorter path through the first bend.

Tricast — a bet requiring you to predict the first, second and third-placed dogs in exact order. Returns are calculated by the CT algorithm and are typically much larger than forecast dividends because the prediction is harder.

Wide runner — a dog that races on the outside of the track through the bends, covering more ground than a rail-runner. Indicated by “w” in form comments. Wide running is a significant disadvantage at Sheffield’s tight circuit, where the extra distance through each bend accumulates over four turns.
