Greyhound Betting Glossary: Every Term You Need to Know

Greyhound racing has its own vocabulary, and half of it is not immediately obvious even to people who bet on other sports. A race card full of abbreviations like QAw, CalcTm, and CSF reads like a foreign language until you learn the terms. A conversation about BOG, BAGS, and SP assumes a shared understanding that new bettors often do not have. This glossary covers the essential terminology from A to Z, with enough context to make each term useful rather than just defined.

A to F

Ante-post — A bet placed before the final field for a race or competition is confirmed. In greyhound racing, ante-post betting is most common on major events like the English Greyhound Derby and the St Leger. If your selection does not make the final, the stake is typically lost.

BAGS — Bookmakers’ Afternoon Greyhound Service. A schedule of behind-closed-doors meetings contracted by bookmakers, running from mid-morning through mid-afternoon at GBGB-licensed tracks. No public admission. The races are streamed live to bookmaker platforms.

Best Odds Guaranteed (BOG) — A bookmaker promotion where you take an early price and, if the Starting Price is higher, receive the higher price. The most valuable routine promotion in greyhound betting.

Bumped (Bmp) — Physical contact between runners during a race. Bmp1 means bumped at the first bend, Bmp2 at the second, and so on. Repeated bumping in a dog’s form suggests it races in congested positions.

Calculated Time (CalcTm) — The race time adjusted for going conditions. The going adjustment is applied to the raw time to produce a normalised figure that allows comparison across different race days and different conditions. The most reliable time metric for form analysis.

Checked (Ck/Crd) — A dog’s progress was impeded by another runner. More significant than bumping because it involves a loss of speed. CrdRnOn means the dog was crowded but continued to compete, which indicates resilience.

Computer Straight Forecast (CSF) — The payout calculation for straight forecast bets. CSF is derived from an algorithm using the Starting Prices of the first and second finishers. The return is not known until after the race.

Each-Way — A bet in two parts: one on the dog to win, one on the dog to place (first or second). The place portion pays at a fraction of the win odds, typically one quarter. Total stake is double the unit stake.

Early Price — Odds offered by a bookmaker before the race, in advance of the Starting Price. Taking an early price locks in the odds at that moment. With BOG, any drift to a higher SP benefits the bettor.

Forecast — A bet predicting the first two finishers. A straight forecast requires the exact order. A reverse forecast covers both possible orders and costs two units. A combination forecast covers multiple dogs in any first-and-second pairing.

G to O

GBGB — Greyhound Board of Great Britain. The self-regulatory body governing licensed greyhound racing in England, Scotland, and Wales. Sets and enforces rules on racing, welfare, doping, and track standards.

Going — The condition of the track surface, assessed before each meeting. Categories: Fast, Normal, Slow, Wet. Going affects race times and favours different running styles. Always check the going before betting.

Going Adjustment — A numerical correction applied to race times to account for track conditions. A positive adjustment means fast going; negative means slow. Used to calculate CalcTm.

Grading — The system that classifies dogs by ability at each track. Grades run from A1 (top) to A11 (bottom). Dogs are promoted after wins and relegated after poor results. Each track maintains its own independent grading system.

Implied Probability — The probability of an outcome as suggested by the odds. Calculated as 1 divided by the decimal odds. If a dog is priced at 4.0 (3/1), the implied probability is 25 percent. Comparing implied probability to your own assessment is how you identify value.

Jackpot — A tote pool bet requiring you to pick the winner of six consecutive races on one card. If nobody wins, the pool rolls over to the next meeting. Rollover jackpots can accumulate into substantial sums.

Kennel — The trainer’s operation, including the dogs registered under their name. Kennel form refers to the collective performance of a trainer’s dogs, which can indicate whether the operation is in a hot or cold period.

Lead (Ld) — The dog led the field at the point described. ALd or DispLd means a disputed lead between two dogs running side by side at the front.

Middle Runner (Mid) — A dog that runs between the rail and the outside, finding a path through the field. Middle runners are typically adaptable but can be squeezed in tight fields.

Open Race — A race open to dogs from any GBGB-licensed track, unlike graded races which are restricted to dogs registered at the host venue. Open races are typically higher quality with bigger prize money.

Overround — The bookmaker’s built-in margin. The sum of implied probabilities for all runners in a race. A fair book totals 100 percent. A typical greyhound overround is 115 to 130 percent. The excess above 100 is the bookmaker’s theoretical profit margin.

P to Z

Pari-Mutuel — The betting system used by the tote, where all bets of a type are pooled and the payout is determined by dividing the pool among winners after a take-out deduction. Returns are not known until after the race.

Quick Away (QAw) — The dog broke fast from the traps. One of the most valuable form indicators for assessing a dog’s early-pace ability. A dog that consistently shows QAw is a reliable trapper.

Rails (Rls) — The inside line of the track, closest to the fence. A rails runner hugs the inside to cover the shortest distance. RlsRn means the dog ran on the rails throughout the race.

Rule 4 (Tattersalls) — A deduction applied to winning bets when a dog is withdrawn from a race after the market has opened. The deduction scale depends on the price of the withdrawn dog. More common in horse racing but applies in greyhound racing too.

Slowly Away (SAw/SlAw) — The dog was slow to leave the traps. A repeated SAw pattern indicates a trapping problem that may not be correctable. Dogs with this tendency lose position in the first few strides regardless of their overall ability.

Split Time — The time recorded at a specific point on the track, usually when the dogs pass the winning line for the first time during the race. A fast split indicates early pace. A slow split with a strong finish indicates a closer.

Starting Price (SP) — The official price at which a dog starts the race, determined by the on-course market at the moment the traps open. The benchmark against which all greyhound bets are measured.

Stayer — A dog that races over longer distances, typically 630 metres and above. Stayers are built for endurance rather than pure sprint speed and tend to be older and heavier than sprint specialists.

Tote — The pari-mutuel betting operation at UK greyhound tracks. Pools include Win, Place, Forecast, Tricast, and Jackpot. Tote dividends are declared after the race based on pool distribution.

Trap Draw — The starting position assigned to each dog. Traps 1 through 6, each with a fixed colour. The draw is typically random in graded races. Trap position significantly affects race outcomes, particularly at tight tracks.

Trial — A non-competitive run at a track, used to assess a dog’s suitability for competitive racing at that venue. Required for dogs entering a new track or returning from a break. Trial times appear on form cards but are not directly comparable to competitive race times.

Tricast — A bet predicting the first, second, and third finishers in exact order. Returns are calculated by the Computer Tricast algorithm and can be substantial, particularly when outsiders fill the places.

Value — A bet where the true probability of the outcome is higher than the implied probability of the odds offered. The foundational concept in profitable betting. A dog at 5/1 that you assess as having a 25 percent chance of winning represents value because the implied probability (16.7 percent) is lower than your estimate.

Wide Runner (W/Wd) — A dog that runs on the outside of the field, away from the rail. Wide runners cover more ground on every bend but avoid congestion. They succeed when their speed compensates for the extra distance.

Using the Glossary to Improve Your Betting Literacy

Terminology is not decoration. Every term in this glossary corresponds to a data point, a rule, or a concept that affects how greyhound races are run, priced, and settled. Knowing the vocabulary means you can read a race card without guessing, follow a race commentary without confusion, and evaluate a betting opportunity on its merits rather than on its surface appearance.

The terms that matter most for day-to-day betting are the ones that appear on the race card: CalcTm, QAw, SAw, Rls, Mid, W, Ld, Bmp, Ck, and the going adjustment. Mastering these gives you the ability to construct a profile of every dog in a race from the printed data. The terms that matter for managing your betting — value, overround, implied probability, bankroll — provide the framework for turning analysis into profitable decisions.

No glossary replaces experience. The terms become meaningful when you see them in context — when you watch a dog marked QAw actually break fast from the traps, when you see a CalcTm figure confirmed by a strong finishing position, when you feel the frustration of a selection marked CkBmp at the second bend. The definitions are the starting point. The experience is what makes them stick.
