One Language, No Confusion

Greyhound racing has its own vocabulary — a mix of betting terminology, track jargon, and form-reading shorthand that insiders use fluently and newcomers find baffling. The distance between understanding a racecard and staring blankly at a grid of abbreviations is often just a dozen unfamiliar terms, and clearing that barrier is one of the fastest ways to move from casual observer to informed punter.

This glossary covers the terms you will encounter most frequently when reading racecards, studying form, placing bets, and following greyhound racing in the UK. It is organised alphabetically for reference, and each definition is written with practical application in mind — not just what the term means, but why it matters for your betting.

A–F Terms

Accumulator. A bet combining multiple selections where the return from each winning leg rolls into the next. All selections must win for the bet to pay out. Also called an acca. Common formats include doubles (two selections), trebles (three), and four-folds (four). The potential return increases with each leg, but so does the probability of losing.

Ante-post. A bet placed on an event before the final declarations or draw have been confirmed. Ante-post bets on greyhound competitions like the Derby are placed weeks before the first round. The advantage is longer prices; the risk is that your selection might be withdrawn without a refund.

BAGS. Bookmakers’ Afternoon Greyhound Service. The system of daytime greyhound meetings run primarily to generate betting content for bookmakers. BAGS fixtures take place on most weekdays at tracks across the UK and are broadcast through SIS to betting shops and online platforms. They form the backbone of greyhound betting volume.

Best Odds Guaranteed (BOG). A bookmaker promotion where your bet is settled at the higher of the price you took and the starting price. If you back a dog at 4/1 and it starts at 6/1, you are paid at 6/1. BOG eliminates the risk of taking an early price that subsequently drifts.

Bumped (Bmp). A racecard notation indicating that a dog made contact with another runner during the race, causing disruption to its stride or position. Bumping is one of the most common causes of below-par performances and is essential context when reading form figures.

Calculated time. An adjusted race time that estimates what a dog would have run without interference. If a dog was bumped or crowded during a race, the calculated time attempts to reflect its true ability. Useful but imprecise — the adjustment involves subjective judgement about how much time was lost.

Combination forecast. A forecast bet covering multiple permutations. Instead of naming one dog to finish first and another second, you select two or more dogs to fill the first two places in any order. The cost increases with the number of dogs selected but the coverage improves.

Crowded (Crd). A racecard notation indicating a dog was squeezed for room between other runners, losing momentum or position. Like bumping, crowding is a legitimate excuse for a poor finishing position and should be factored into your assessment of the form.

Each-way. A bet in two parts: one on the dog to win and one on the dog to place (finish first or second in greyhound racing). If the dog wins, both parts pay out. If it finishes second, only the place part pays, at a fraction of the win odds (typically one quarter in greyhound racing).

Early pace (EP). A racecard notation indicating a dog showed speed in the early stages of the race, typically reaching the first bend at or near the front of the field. Dogs with consistent EP notations are front-runners whose trap draw is particularly important.

Faded (Fdd). A racecard notation indicating the dog weakened in the closing stages of the race, losing ground after being competitive earlier. Fading can indicate a lack of stamina for the distance, a dog that is overtrained, or one that spent too much energy in the early stages.

Forecast. A bet requiring you to predict the first and second finishers in exact order. Straight forecasts pay more than combination forecasts because the probability of getting the exact order correct is lower. Available both as fixed-odds bets and through the Tote pool.

G–P Terms

GBGB. Greyhound Board of Great Britain. The regulatory body that governs licensed greyhound racing in the UK. The GBGB sets racing rules, licenses tracks and trainers, oversees welfare standards, manages the grading system, and conducts drug testing. Races run under GBGB rules are the basis of the regulated greyhound betting market.

Grade. The classification assigned to a dog based on its recent racing times at a specific track. Grades range from A1 (highest) to A10 or A11 (lowest), depending on the venue. The grading system aims to produce competitive fields by matching dogs of similar ability. Grades are track-specific — a dog graded A3 at Romford might be graded differently at Monmore.

Grader. The racing manager responsible for allocating dogs to races and grades at a specific track. The grader decides which dogs race in which events, assigns trap draws based on running style, and manages the competitive balance of each card. Their decisions directly influence the quality of each field and, by extension, the betting market.

Hare. The mechanical lure that the dogs chase around the track. Most UK tracks use the Outside Swaffham hare, which runs on a rail around the outer edge of the circuit. The hare starts before the traps open and maintains a fixed distance ahead of the field throughout the race.

Hurdle race. A greyhound race featuring low barriers on the straights that the dogs must clear while running. Hurdle racing requires a different skill set from flat racing, and form from hurdle events is assessed separately. Not all tracks stage hurdle races.

Jackpot. A Tote pool bet requiring the selection of winners in multiple consecutive races. If no ticket selects all winners correctly, the pool rolls over to the next meeting. Jackpot bets offer large potential payouts but extremely low probabilities of success.

Kennel. The trainer’s operation, encompassing the dogs in their care and the facilities where they are housed and trained. Kennel form — the collective performance of all dogs from a single trainer — is a useful analytical metric that reflects the current health and competitiveness of the training operation.

Led. A racecard notation indicating the dog led at some point during the race. A dog noted as having led but not won typically led early and was overtaken later, which can indicate front-running ability but a lack of stamina or a tendency to be caught.

Middle distance. Races covering approximately 515 to 630 metres, typically run over six bends. Middle-distance events test a combination of speed and stamina and include some of the most prestigious open races on the UK calendar.

Nap. A tipster’s most confident selection of the day. The term originates from the card game Napoleon and is widely used across horse and greyhound racing. A nap is presented as the strongest bet on the card.

Open race. A race without grade restrictions, open to any dog that meets the entry criteria. Open events attract the best dogs and carry higher prize money than graded races. They are the greyhound equivalent of Group races in horse racing.

Place. In greyhound racing, a dog places if it finishes first or second. Each-way bets pay out on a place finish at a fraction of the win odds. Some Tote place pools may extend to the first three finishers depending on the bet type.

Q–Z Terms

Ran on (RnOn). A racecard notation indicating the dog finished strongly, gaining ground in the closing stages of the race. Dogs with consistent RnOn notations are closers — they tend to race in midfield early and finish with a late surge. These dogs are often undervalued by the market because their finishing positions can understate their ability when they encounter early traffic.

Reserve. A substitute runner held on standby in case a declared dog is withdrawn before the race. The reserve wears a distinctive jacket and is drawn from the pool of dogs available at the meeting. If no withdrawal occurs, the reserve does not run.

Rule 4. A deduction applied to winning bets when a dog is withdrawn from a race after betting has opened. The deduction compensates for the removal of a competitor from the field, which changes the probability of the remaining runners winning. The size of the deduction depends on the price of the withdrawn dog.

Sectional time. The time recorded for a specific portion of a race, typically the split from trap opening to the first bend (first sectional) and from the first bend to the finish (closing sectional). Sectional times reveal how a race was run and are essential for identifying running styles and assessing the quality of a performance beyond the finishing position.

SIS. Satellite Information Services. The company that provides live racing feeds to betting shops and online bookmakers. SIS broadcasts cover the majority of UK greyhound meetings, particularly the BAGS afternoon fixtures.

SP (Starting Price). The officially returned price at the time the traps open. The SP is determined by the state of the market at the off and is used to settle bets placed at starting price. Punters can choose to bet at SP or take a fixed early price before the race.

Sprint. A race over a short distance, typically 210 to 285 metres, covering two bends. Sprint races are dominated by the trap break and early pace, with inside trap draws carrying a significant advantage at most tracks.

Stayer. A dog that specialises in longer distances, typically 630 metres and above. Stayers tend to be lighter in frame and more efficient in their stride than sprinters, with the stamina to sustain pace through multiple bends.

Tote. The pool betting operator at UK greyhound tracks. Tote bets are pooled together and dividends are declared after the race based on the distribution of money in the pool. Tote dividends can be higher or lower than bookmaker fixed odds depending on the popularity of the winning selection.

Trap. The starting box from which a dog breaks at the beginning of a race. Six traps are used in standard UK greyhound racing, numbered one (inside rail) to six (outside), each with a designated jacket colour. The trap draw influences the race outcome, particularly at tracks with short run-ins to the first bend.

Tricast. A bet requiring you to predict the first, second, and third finishers in exact order. Tricasts offer the largest payouts of the standard bet types but have the lowest probability of success. Available as straight (exact order) or combination (any order) formats.

Wide runner. A dog that tends to race towards the outside of the track rather than following the rail. Wide running covers more ground and is generally a disadvantage, but some dogs perform better with space around them and produce their best results from outside trap draws. Wide-running dogs are often better suited to tracks with more generous bend radii.

Terminology Is the First Barrier to Confidence

Every unfamiliar term on a racecard is a small barrier to understanding. Each one you learn removes that barrier and adds to the clarity with which you can assess a race. The difference between a punter who glances at the form and one who reads it — who understands what Crd means, why EP matters, how a calculated time adjusts for interference — is not experience or intelligence. It is vocabulary.

This glossary is not exhaustive. Greyhound racing generates new terminology as the sport evolves, and regional variations exist between tracks. But the terms listed here cover the vast majority of what you will encounter in racecards, results pages, betting slips, and conversations about the sport. Learn them once, refer back when needed, and let the language of the sport become part of your analytical toolkit rather than an obstacle to it.

The racecard is a conversation between the track and the punter, conducted in a shared language. The more of that language you understand, the more information the card gives you — and the better equipped you are to turn that information into sound betting decisions.
