Small-field races with well-fancied favourites tend to carry lower overrounds (closer to 110 per cent) because the market is more efficient and bookmakers compete harder on the headline price of the favourite. The overround also tells you something about the race itself. The overround is 5.9 per cent, meaning the bookmaker has built a theoretical edge of just under 6 per cent into the market. It is the bookmaker’s theoretical profit margin before a single bet is settled. In practice, they always sum to more — typically between 110 and 130 per cent for horse racing — and that excess is the overround. In a perfectly fair market with no margin, the implied probabilities of all runners in a race would sum to exactly 100 per cent.
If you bet at a bookmaker with a consistently higher overround, you need a higher strike rate just to break even. Checking the overround before you bet is not something most punters do, but it takes less than a minute with a calculator or an odds comparison site. The worst overrounds appear in ante-post markets, where the uncertainty justifies — in the bookmaker’s view — margins that can reach extraordinary levels.
If the exchange is at 7.0 and the bookmaker is at 6/1, the prices are closer, and after exchange commission the bookmaker might even be marginally better. If the exchange back price is 8.0 and the best bookmaker is offering 6/1, the bookmaker is taking a significantly wider margin on that horse. Open Betfair or Smarkets and look at the back price on your selection. For any given horse, you can see the best available price highlighted, and the difference between the best and worst price is often two or three points of odds — the difference between 7/1 and 5/1 on the same horse in the same race.
The app interface prioritises racing with dedicated sections for today’s cards. Racing-specific features include detailed form guides and early prices on major races. Each major operator brings distinct strengths for racing specialists, from BOG activation times to streaming quality to the depth of their racing-specific features. Bookmakers competing for turnover frequently extend four places to five or even six on Cheltenham Festival handicaps, Grand National day, and similar high-profile cards. Each-way betting offers value in specific circumstances. On a £10 each-way bet, that difference is £5—pure margin handed to you when bookmakers compete on place terms.
On horses that drift — less money than expected, price lengthening — BOG gives you the benefit of the higher SP. On horses that are supported in the market — money coming in, price shortening — BOG adds nothing, because the SP is lower than the price you took. Check the exchange price on your selection before placing with a bookmaker. Flutter Entertainment, which owns Betfair, reported global revenue of $14 billion in 2024 across 13.9 million average monthly users, but the exchange is only one part of that portfolio, and liquidity varies enormously by market. On a Monday afternoon novice hurdle at a minor track, liquidity is thin.
The difference between taking 5/1 at one bookmaker and 11/2 at another might look trivial on paper. It is a skill that separates profitable punters from those who slowly bleed their bankrolls to bookmaker margins. Finding the best horse racing odds in the UK is not a matter of luck. Now that you have a basic understanding of how odds work, and the different ways they are represented, you can compare them online and get the best bet possible.

Despite these caps, BOG remains the single most consistently valuable promotion in horse racing. And some operators apply BOG only to bets placed after a certain time in the morning, which means very early ante-post-style wagers do not qualify. There are practical considerations that limit BOG value. Using the exchange as a benchmark — even if you ultimately bet with a bookmaker — is one of the most effective habits a punter can develop. If the exchange offers 7.0 and the bookmaker offers 5/1, the bookmaker is taking a significantly larger margin on that runner, and you should either back on the exchange or find a bookmaker whose price is closer to the exchange level.
