Some racing exists because a shop needed something to show
If you have ever wondered why greyhound races are running at two in the afternoon on a Tuesday in front of almost nobody, the answer is not sporting demand. Some of that racing is viewable in betting shops through a dedicated service supplying afternoon greyhound coverage, and the schedule exists because shops need a continuous programme between horse races. That is worth saying plainly rather than treating as a scandal: it explains why the graded card, rather than the showpiece competition, is the backbone of the sport, and it explains why an afternoon meeting looks the way it does. It also means the racing you are watching in a shop was, in part, scheduled for the shop.
The two kinds of racing on a British greyhound calendar
Graded racing and open competition sit side by side, and the categories that govern the latter are defined by prize money.
Graded racing is the daily supply
Graded races are the ones staged routinely at each track, with varying prize money, and some of that racing is shown in betting shops via the bookmakers' afternoon greyhound service. It is the core of most stadiums' programmes.
Category one is the top tier
Open competitions are categorised by minimum prize money. Category one races must carry at least £12,500, may be run over one to four rounds, and must be completed within fifteen days except in special circumstances, and within eighteen days in any event.
Categories two and three below it
Category two races require minimum prize money of £5,000 over one, two or three rounds within fifteen days. Category three requires £1,000 over one or two rounds within nine days, or £500 if staged over a single day.
Invitation and minor opens
An invitation race is a special open staged in support of other opens on the same night, with runners invited rather than entered normally, carrying minimum prize money of £750. Any other open race is a minor open, with minimum added money of £150.
The questions that arrive most often
Why is there greyhound racing in the middle of the afternoon?
Because betting shops need a continuous supply of events, and a dedicated bookmakers' afternoon greyhound service exists to provide it. Some graded racing is staged and shown specifically so that a shop screen has something running between horse races. That does not make the racing less real — the same rules, vetting and grading apply — but it does explain a schedule that makes no sense if you assume the crowd at the stadium is the audience.
What is the difference between graded and open racing?
Graded racing is the routine programme at a track, with dogs sorted into classes by the racing manager and prize money varying. Open racing is competition that draws entries more widely and is formally categorised by minimum prize money: category one at £12,500 or more, category two at £5,000 or more, category three at £1,000 or more, invitation races at £750 and minor opens with £150 minimum added money. The categories also set how many rounds may be run and over how many days.
Does a bigger prize mean a better race to bet on?
It means a higher category and, ordinarily, a stronger field, but it says nothing at all about whether a bet on it is more likely to come in. Prize money describes the competition, not your chances, and no category of race is easier to predict than another. The reason to notice the category is that it tells you what kind of field has been assembled, which is context — the outcome itself remains unpredictable in every category.
