Greyhound Betting Glossary | Every Term a Punter Needs to Know

The Language of the Dogs

Greyhound racing and betting have their own vocabulary — a mix of racing terminology, betting jargon, and track-specific language that can be impenetrable to newcomers and occasionally confusing even to experienced punters. This glossary defines the key terms you will encounter when reading race cards, studying form, placing bets, and following greyhound racing in the UK. Terms are grouped alphabetically for reference.

A–F

Accumulator (Acca): A bet combining multiple selections across different races. All selections must win for the bet to pay out. Each winning leg’s return becomes the stake for the next. Also called a multiple.

Ante-post: A bet placed on a future event before the final field is confirmed. Ante-post bets on greyhounds are most common for the Derby, St Leger, and other major competitions. Stakes are lost if the dog does not run — non-runner, no refund.

BAGS: Bookmakers’ Afternoon Greyhound Service. The framework that provides daily daytime greyhound racing fixtures for off-course betting. BAGS meetings are staged at GBGB-licensed tracks and run throughout the afternoon.

Best Odds Guaranteed (BOG): A bookmaker promotion that pays you the higher of your early price or the starting price. If SP exceeds the price you took, you receive SP. If your price was better, you keep it. Available from most major UK bookmakers on greyhound racing.

Board price: The odds displayed by a bookmaker at a given time before the race. Also referred to as early price or fixed price. Distinct from starting price.

Calculated time: An adjusted race time that estimates what a dog would have run with a clear passage, accounting for interference, bumping, and wide running. Published by specialist data providers.

Closer: A dog whose running style involves settling behind the early pace and finishing strongly in the final stages of the race. Identified by fast run-home sectional times relative to slow early splits.

Combination forecast: A forecast bet covering all possible finishing orders of three or more selected dogs in first and second place. Three dogs produce six permutations; four dogs produce twelve.

Combination tricast: A tricast bet covering all possible finishing orders of three or more selected dogs in first, second, and third. Three dogs produce six permutations; four dogs produce twenty-four.

Double: An accumulator with two selections. Both must win for the bet to pay out.

Drift: When a dog’s odds lengthen (increase) in the market before a race. A dog that drifts from 3/1 to 5/1 is receiving less support from bettors.

Each way: Two bets in one — a win bet and a place bet at a fraction of the win odds. In six-runner greyhound races, two places are typically paid at a quarter of the win odds.

Early price (EP): The fixed odds offered by a bookmaker before the race, taken at the time of bet placement. Distinct from starting price.

Forecast: A bet predicting which dogs will finish first and second. Can be straight (exact order), reverse (either order), or combination (multiple dogs).

Form: A dog’s recent racing record, typically displayed as finishing positions from the last six races. The primary data source for assessing a dog’s current ability and consistency.

Front-runner: A dog that breaks sharply from the traps and aims to lead the field from the first bend to the finish. Identified by fast early sectional times.

G–P

GBGB: Greyhound Board of Great Britain. The governing body for licensed greyhound racing in England and Wales. Responsible for regulation, licensing, and welfare standards.

Going: The condition of the track surface, affected primarily by weather. Descriptions include fast (dry, firm sand), standard, and heavy (rain-affected, slow).

Grade: The classification level assigned to a greyhound based on recent performance. A1 is the highest graded level; A10 is the lowest. Dogs move up or down in grade based on results. Separate categories exist for sprints (D), staying races (S), and hurdles (H).

Hare: The mechanical lure that greyhounds chase during a race. Runs on a rail around the inside of the track. Also called the bunny or lure.

Handicap: A race in which dogs of different grades compete from staggered starting positions to compensate for differences in ability.

Implied probability: The probability of an outcome as suggested by the odds. Calculated by dividing 1 by the decimal odds. For example, 4/1 (5.00 decimal) implies a 20% probability.

Lucky 15: A system bet on four selections comprising four singles, six doubles, four trebles, and one four-fold — fifteen bets in total. Offers consolation bonuses on some platforms if only one selection wins.

Non-runner: A dog that is withdrawn from a race before it takes place. In greyhound racing, non-runners are often replaced by reserve dogs to maintain a six-dog field.

Open race: A race that sits outside the standard grading ladder, typically inviting the best dogs at a track or from multiple tracks. Major competitions such as the Derby are run as open races.

Overround: The bookmaker’s built-in profit margin on a market, expressed as the amount by which the total implied probabilities of all outcomes exceed 100%. An overround of 120% means the bookmaker has a 20% margin.

Pace mapping: The analytical process of predicting the shape of a race based on each dog’s running style and trap draw — identifying which dogs will lead, which will chase, and which will close.

Place bet: A bet on a dog to finish in the first two (in a six-runner race). Place terms vary by field size.

Q–Z

Railer: A dog that naturally runs close to the inside rail through the bends, covering the shortest distance around the track. Typically drawn in low traps by the racing manager.

Reserve: A standby dog listed on the race card that replaces a withdrawn runner. Reserves are identified as R1 and R2 and enter the race in the withdrawn dog’s trap.

Reverse forecast: A forecast bet covering both possible finishing orders of two selected dogs. Equivalent to two straight forecasts and costs twice a single straight forecast stake.

Rule 4: A deduction applied to winning bets when a runner is withdrawn after odds have been published. The deduction is proportional to the withdrawn dog’s price and is expressed as pence in the pound of profit.

Run-home time: The sectional time covering the final segment of a race, from the last bend to the finish line. Indicates a dog’s finishing speed and stamina.

Sectional time: The time taken by a dog to complete a specific portion of the race distance. The most commonly recorded sectionals are the first-bend time and the run-home time.

SP (Starting price): The official odds on a runner at the moment the traps open, determined by the on-course market. Bets placed at SP settle at whatever price is declared.

Steamer: A dog whose odds shorten significantly in the market before a race, indicating strong support from bettors. The opposite of a drifter.

Straight forecast: A bet predicting the exact first and second finishers in a race, in the correct order.

Straight tricast: A bet predicting the exact first, second, and third finishers in a race, in the correct order.

Strike rate: The percentage of a bettor’s or trainer’s selections that win. Used as a measure of effectiveness over time.

Trap: The starting box from which a greyhound begins a race. Numbered 1 through 6 from the inside rail outward, each associated with a jacket colour: red (1), blue (2), white (3), black (4), orange (5), black and white stripes (6).

Trap bias: A statistical tendency for certain trap positions to produce more winners than others at a specific track, driven by track geometry and seeding patterns.

Treble: An accumulator with three selections. All three must win for the bet to pay out.

Tricast: A bet predicting the first three finishers in a race. Can be straight (exact order) or combination (any order among selected dogs).

Trixie: A system bet on three selections comprising three doubles and one treble — four bets in total. Two of the three selections must win for any return.

Wide runner: A dog that naturally runs on the outside of the field through the bends, covering more ground but avoiding inside traffic. Typically drawn in high traps.

Yankee: A system bet on four selections comprising six doubles, four trebles, and one four-fold — eleven bets in total. Two of the four selections must win for any return.
