Best Odds Guaranteed in Horse Racing: How BOG Works and Why It Matters for Your Bet

Early Price, Starting Price, Best Price — BOG Explained
I backed a horse at 8/1 on a Tuesday evening. By post time on Saturday, it had been backed down to 9/2. Without Best Odds Guaranteed, I would have been stuck with the shorter price because the starting price was lower than my early price. With BOG, the bookmaker paid me at 8/1 — the price I originally took. That single promotion turned a decent return into a significantly better one, and I did not have to lift a finger.
Best Odds Guaranteed is one of the most valuable features a UK bookmaker offers to horse racing bettors, and it is one of the least understood by beginners. The concept is simple: if you take a price on a horse and the starting price is higher, the bookmaker pays you at whichever is better. If the SP drifts out to 12/1 but you took 8/1, you get 12/1. If it comes in to 5/1, you keep your 8/1. You always get the best of both worlds.
The average turnover per race on Premier fixtures held steady in 2025, while Core fixtures dropped by over 8 percent. That divergence matters because BOG is primarily offered on UK and Irish racing — the markets where turnover is most concentrated. It is not a gimmick. It is a genuine price advantage that directly affects your returns on every qualifying bet.
How Best Odds Guaranteed Adjusts Your Payout
Let me walk through the arithmetic, because the real value of BOG only becomes clear when you see numbers. Suppose you stake 10 pounds on a horse at 6/1 on the morning of the race. By the time the stalls open, the horse has attracted heavy support and its starting price is 4/1.
Without BOG, some bookmakers would settle at the starting price if you had taken an early price and the SP was lower. With BOG, you are locked in at 6/1. Your return is 70 pounds (60 profit plus 10 stake) instead of 50 (40 profit plus 10 stake). That is a 40 percent increase in profit from the same bet, purely because the promotion existed.
Now flip it. You take 6/1 in the morning, but money comes for other horses and your selection drifts to 10/1 at the off. BOG pays you at 10/1 — the starting price, because it is higher. Your return jumps to 110 pounds. This scenario is less discussed but arguably more valuable. Horses that drift in the market often do so for a reason, but sometimes the market is simply wrong. When it is, BOG ensures you capture the full upside.
One important detail: BOG compares your taken price to the official starting price returned by the racecourse, not to the price available on any other bookmaker’s site. The SP is determined by on-course bookmakers and is the same across the industry. Your taken price is whatever odds you locked in when you placed the bet.
When BOG Applies — and When It Doesn’t
Last summer, I confidently placed an ante-post bet on a Royal Ascot runner at 20/1, assuming BOG would protect me if the price moved. It did not. BOG does not cover ante-post bets. That distinction cost me nothing in the end — the horse finished mid-pack — but it was a useful reminder that every promotion has boundaries.
The standard conditions across most UK bookmakers follow a consistent pattern. BOG applies to win and each-way bets on UK and Irish horse racing, placed at fixed odds, on the day of the race. Some operators extend it to races in other jurisdictions, but that is the exception rather than the rule.
Bets placed the night before, when early prices are first published, are usually covered. Bets placed weeks in advance — ante-post — are not. Tote bets are excluded because pool betting does not use fixed odds. Enhanced-odds promotions and price boosts are typically excluded too: if the bookmaker has already inflated the price artificially, BOG does not apply on top of that.
Maximum payout limits also apply. If BOG triggers a very large uplift — say, you took 10/1 and the SP returned 50/1 — the bookmaker may cap the BOG element. These caps vary by operator and are not always prominently displayed. The small print matters, particularly for larger stakes.
Using BOG as Part of Your Betting Approach
BOG is not a strategy in itself, but it amplifies good habits. If you are the type of bettor who studies the card in the morning, forms an opinion, and takes a price early, BOG rewards that discipline. You lock in value when you see it, knowing you are protected if the market moves against you and rewarded if it moves in your favour.
The practical implication is straightforward: when two bookmakers offer near-identical odds on a horse, and one provides BOG while the other does not, choose the one with BOG every single time. Over a season of regular betting, the cumulative effect of taking the best price on every race adds up to a meaningful difference in overall returns. I have tracked my own results with and without BOG adjustments over a full flat season. The BOG uplift added roughly 6 percent to my total returns across several hundred bets. On any individual race, the difference might be trivial. Across a year, it is not.
There is a behavioural benefit too. BOG removes the anxiety of taking a price too early. Without it, you might hesitate, waiting for the market to settle, worried about being caught on the wrong side of a price movement. That hesitation often leads to missing the best odds entirely. With BOG in place, the decision is easier: if you like the horse and the price looks fair, take it. The promotion handles the rest.

Does Best Odds Guaranteed apply to ante-post bets?
No. BOG is only available on bets placed at fixed odds on or close to the day of the race. Ante-post bets, placed weeks or months in advance, are excluded from BOG across virtually all UK bookmakers. The price you take at the time of an ante-post bet is the price you receive.
Do all UK bookmakers offer BOG on every race?
Most major UK bookmakers offer BOG on UK and Irish horse racing as a standard feature, but the specifics vary. Some extend it to all races, others limit it to certain meetings or bet types. A few smaller operators do not offer it at all. Always confirm that BOG is active for the specific race and bet type before placing your wager.
