Greyhound Racing Grades — A1 to A10 Explained

The League Table You Did Not Know Existed

Every greyhound competing at a licensed UK track is assigned a grade. That grade determines which races the dog can enter, which dogs it competes against, and — from a betting perspective — how competitive the field is likely to be. It is, in effect, a league table: A1 is the top division, A10 is the bottom, and dogs move between grades based on their results. Win races, move up. Lose races, move down. The system is administered by the Greyhound Board of Great Britain (GBGB).

Most casual bettors ignore grading entirely. They look at the form figures, check the odds, and place their bet without asking what grade the race is. That is a mistake. The grade tells you something the form figures alone cannot: the quality of opposition the dog has been facing and how it is likely to cope with the dogs alongside it tonight. A dog that has been winning in A6 races and is now stepping up to A4 faces a significant jump in class. Its form might look impressive on paper, but the dogs it beat last week are two grades below the ones it is racing against now.

Understanding the grading system does not require deep knowledge of GBGB administration. It requires knowing what each grade level means in practical terms, how promotions and demotions work, and why the grade of a race should influence your betting decisions.

A1 to A10 — What Each Grade Means

The grading system in UK greyhound racing runs from A1 at the top to A10 at the bottom, though not every track uses the full range. Most tracks operate between A1 and A7 or A8, with the lower grades appearing mainly at smaller or less competitive venues. The letter “A” stands for the standard adult grading tier. Other prefixes exist — D for puppies, S for stayers, H for hurdles, and OR for open races — but the A-grade structure is the backbone of the system.

A1 represents the fastest, most competitive greyhounds at the track. These are dogs with consistently quick times, strong recent form, and the physical ability to compete at the highest level the venue offers. At a track like Romford or Hove, an A1 dog is a genuine elite performer. At a smaller venue, A1 might represent a slightly lower absolute standard, but it still denotes the best dogs racing there.

A2 and A3 are the upper-middle grades — dogs that are competitive but not quite at the peak. Many experienced, reliable racing dogs spend the bulk of their careers oscillating between A2 and A4 as their form fluctuates. These grades produce some of the most competitive racing for bettors because the dogs are closely matched and form analysis is particularly relevant.

A4 to A6 are the mid-grades, and this is where the majority of BAGS afternoon racing sits. Dogs in these grades are capable, race-fit animals that win and lose in roughly equal measure depending on conditions, draw, and the form cycle. For bettors, the mid-grades are where data-driven approaches produce the most consistent returns, because the fields are competitive enough that no single dog dominates, yet the dogs are experienced enough that their form patterns are readable.

A7 and below are the lower grades. Dogs at this level are either young and still developing, older and slowing down, or simply not fast enough to compete higher. Lower-grade races can be unpredictable — the form is less reliable, the dogs are less consistent, and upsets are more common. Some bettors avoid these grades entirely. Others see opportunity in the volatility, particularly in forecast and tricast markets where outsized dividends are more frequent.

The grading is track-specific, which is an important detail. An A3 dog at Romford is not necessarily the same standard as an A3 dog at Kinsley. Larger, more competitive tracks attract better dogs, so their grade thresholds are higher. When a dog transfers from one track to another, the racing manager at the new venue reassesses and may assign a different grade. This is worth noting when a dog appears at a new track for the first time — its previous grade is indicative, not definitive.

Open Races, Handicaps and Puppy Events

The A-grade system covers the standard graded races that make up the majority of UK greyhound meetings. But several other race types sit outside the grading ladder, and each has its own characteristics for bettors.

Open races are the prestige events. They have no grade restriction — any dog can enter, and the field is selected based on ability and invitation. Open races at major tracks like Hove, Romford, and Monmore attract the best dogs from across the region, and sometimes the country. The English Greyhound Derby heats, for instance, are open events. For bettors, open races present a different challenge: the form comparison is harder because the dogs may come from different tracks with different grading standards, and the fields often include one or two clearly superior dogs alongside more modest competitors. This creates lopsided markets where the favourite is very short and the place betting becomes more interesting than the win.

Handicap races are less common in greyhound racing than in horse racing, but they do exist at some tracks. In a handicap, dogs start from different trap distances based on their grading — slower dogs receive a head start. The aim is to produce a race where all dogs finish at roughly the same time, making the outcome harder to predict. Handicap markets tend to offer longer odds across the board and can reward bettors who understand how the stagger distances affect the first-bend dynamic.

Puppy races are restricted to dogs under a certain age — typically under two years old, though definitions vary by competition. Puppy events are important in the greyhound calendar because they showcase future talent, and the Puppy Derby is one of the year’s headline events. From a betting standpoint, puppy races are volatile. Young dogs are still developing their racing style, and their form can change dramatically from week to week. One run they look like a future A1 performer; the next they miss the break and finish last. Treat puppy form with caution, and expect the unexpected.

Sprint and stayer races are graded separately using S-prefixes for stayers and sometimes distinct grade ladders. A dog might be graded A3 at standard distance but S2 in staying events if it excels over longer trips. When betting on non-standard distances, check the dog’s grade at that specific distance rather than assuming its flat-grade rating applies.

Why Grade Matters for Betting

Grade is a filter. Used correctly, it prevents you from making bets that look good on paper but collapse under scrutiny.

The most common grading trap for bettors is the dog stepping up in class. A dog that has won two of its last three races in A5 looks like a solid selection. Its form figures show 211, the odds are 3/1, and the racecard looks encouraging. But tonight it is running in an A3 race because those wins triggered a promotion. The dogs alongside it are faster, more experienced at this level, and better suited to the pace. The form that looked impressive in A5 may not hold up in A3. Checking whether a dog is racing at its established grade or has recently been promoted is a thirty-second task that can save you from backing a dog out of its depth.

The reverse scenario also creates opportunities. A dog dropping down from A3 to A5 after a string of poor results may be facing easier competition than it has encountered in weeks. If the poor form was caused by bad draw or first-bend interference rather than a genuine decline in ability, the drop in grade gives it a chance to bounce back. These class drops are one of the most reliable betting angles in greyhound racing: a capable dog in a bad run, returning to a grade where its ability stands out.

Grade also helps you calibrate your expectations for the market. In A1 and A2 races, the favourite is more likely to win because the field quality is high and the best dog tends to be clearly identifiable. In A6 and A7 races, favourites win less often because the field is more unpredictable. Adjusting your staking approach — perhaps favouring each way or forecast bets in lower grades and win bets in higher grades — is a practical application of grading knowledge.

Finally, grade matters for forecast and tricast construction. In a tightly graded race where all six dogs are A4, the finishing order is hard to predict and the dividends tend to be higher. In a race where one A1 dog is dropped into a mixed field for a specific event, the winner may be obvious but the place finishers become harder to call. Different grading contexts suit different bet types.

Grade the Dog, Then Grade the Race

The grading system exists to produce competitive racing — dogs of similar ability racing against each other. For the bettor, it provides a framework that adds depth to every racecard analysis. Knowing the grade tells you the standard of the race. Knowing whether a dog is moving up, moving down, or staying at its level tells you how its recent form should be interpreted.

It takes very little effort to incorporate grading into your pre-race analysis. Check the race grade on the card. Check each dog’s recent grade history — most racecard platforms show this alongside the form figures. Note any promotions or demotions. Then factor that context into your assessment of the odds. A dog at the right grade with good form is a stronger proposition than a dog with identical form that has just been promoted beyond its comfort zone.

Grade the dog first. Then grade the race. Then place the bet.
