Best Odds Guaranteed is one of the most valuable promotions in horse racing betting, and it costs you nothing to use. The concept is straightforward: you take a price on a horse in the morning or at any point before the race, and if the Starting Price (SP) turns out to be higher, the bookmaker pays you at the bigger number instead. You get the best of both prices — the security of locking in early and the upside of any late drift in the market.
BOG has been a fixture of UK racing for years, yet a surprising number of punters either do not know it exists or do not fully understand when it applies. Given that a single BOG payout can turn a modest win into a significantly larger one, it is worth knowing exactly how the mechanism works, which bookmakers offer it, and where the fine print narrows the deal.
How Best Odds Guaranteed Works: Step-by-Step BOG Guide
The process is automatic at most bookmakers that offer BOG. You do not need to opt in, tick a box, or enter a code. Here is how it works in practice.
Step one: you find a horse you want to back. Let us say it is priced at 8/1 at 10am on race day. You place your bet at 8/1 — this is now your fixed price, locked in and confirmed on your bet slip. Step two: the race approaches, and the on-course market moves. By the time the race goes off, the Starting Price is returned at 12/1. The horse has drifted — more money came for other runners, or the horse attracted less support than expected. Step three: your horse wins. Under normal circumstances, you would be paid at 8/1 because that is the price you took. With BOG, the bookmaker automatically upgrades your payout to 12/1. You receive the higher of the two prices without having to ask.
The reverse scenario is equally important to understand. If you take 8/1 in the morning and the SP contracts to 5/1 — the horse has been backed, its price has shortened — BOG still pays you at 8/1. You locked in the bigger number, and the bookmaker honours it. This is the core appeal: you are protected against both outcomes. If the price drifts, you benefit. If the price shortens, you keep your early value.
BOG matters most on races where the market moves significantly between the morning prices and the off. BHA data shows that turnover on Premier racing rose 1.1% while Core fixture turnover fell 8.1% — a gap that reflects heavier money flowing into the big meetings. On Premier cards with deep markets, prices can shift by several points between morning and afternoon. On quieter Core fixtures, the movements may be smaller, but BOG still captures any difference. The more volatile the market, the more BOG is worth to you.
A Real Payout Example — Morning Price vs SP
Numbers tell the story better than theory, so here is a worked example that shows the difference BOG can make to your returns.
You back a horse at 6/1 with a £10 win stake at 9.30am. The race is a competitive handicap at Newbury with 14 runners. By the time the market settles at the off, the horse’s SP is 10/1 — it has drifted because the favourite shortened, pulling other prices out. Your horse wins.
Without BOG, your payout would be 6/1 × £10 = £60 profit, plus your £10 stake back = £70 total return. With BOG, the bookmaker automatically pays at 10/1: £100 profit plus the £10 stake = £110 total return. The difference is £40 in pure profit from a single bet — and you did nothing to earn it beyond choosing a bookmaker that offers the promotion.
Now consider the same scenario each-way. A £10 each-way bet at 6/1 means £10 on the win and £10 on the place, £20 total outlay. With standard 1/4 place terms and BOG upgrading to 10/1, your win part pays at 10/1 (£100 + £10 = £110) and your place part pays at 10/4, which is 2.5/1 (£25 + £10 = £35). Total return: £145 from a £20 stake. Without BOG, the win part pays at 6/1 (£60 + £10 = £70) and the place part at 6/4 (£15 + £10 = £25). Total return: £95. BOG added £50 to your each-way payout — a 53% increase.
These are not extreme examples. A four-point drift between morning price and SP is common on busy Saturday cards, and the compounding effect across multiple winning bets over a season is substantial. BOG is, quietly, one of the biggest edges available to recreational punters.
Which Bookmakers Offer BOG on Horse Racing?
Most major UK-licensed bookmakers offer Best Odds Guaranteed on horse racing, though the specifics vary. The big names — bet365, William Hill, Paddy Power, Betfair Sportsbook, Ladbrokes, Coral and Sky Bet — all run BOG promotions on UK and Irish horse racing as standard. Some extend it to selected international meetings; others limit it strictly to domestic fixtures.
The shift towards online betting has made BOG more accessible than ever. According to the Gambling Commission’s industry statistics, the number of licensed betting shops in the UK has fallen to 5,825 — a 22.8% decline from pre-pandemic levels — a contraction that underscores how much of the market has moved online, where BOG is a standard feature rather than an exception. In a physical betting shop, BOG is less commonly offered; the promotion is primarily an online and mobile benefit, designed to attract and retain digital customers.
It is worth checking whether your bookmaker applies BOG automatically or requires you to opt in. The majority of operators apply it by default to all qualifying bets, but a handful require you to check a setting in your account preferences. If you are not sure, place a small test bet on a race where the SP is likely to move, then check whether the settlement reflects the higher price. The difference will be obvious on the bet history screen.
Smaller or newer bookmakers sometimes use BOG as a headline acquisition tool, offering it prominently to attract customers from larger operators. The promotion itself is identical in principle — you receive the higher payout — but the terms may differ in the detail. Maximum payout caps, excluded race types and time-of-day restrictions are all areas where the small print can vary between operators.
BOG Limitations — When It Doesn’t Apply
BOG is generous, but it is not unconditional. Every bookmaker attaches terms, and knowing the common limitations prevents unpleasant surprises when you check your settled bets.
The most frequent restriction is a maximum payout cap. A bookmaker might offer BOG but limit the SP upgrade to a maximum of, say, 20/1 or 50/1. If you take a horse at 8/1 and the SP drifts to 66/1, you may only be paid at the capped figure rather than the full SP. These caps are disclosed in the terms and conditions, typically on the BOG promotions page. Always check.
Timing restrictions are another common condition. Some bookmakers only apply BOG to bets placed on the day of the race, excluding ante-post wagers entirely. Others set a cutoff — bets placed before a certain time (often the evening before the race) may not qualify. If you routinely bet the night before a meeting, this restriction matters.
BOG typically applies only to win and each-way singles. Forecasts, tricasts, accumulators and other multiple bets are usually excluded, although some bookmakers extend BOG to the individual legs of an accumulator — it depends on the operator. Enhanced odds and price boost promotions often sit outside BOG as well: if you take a boosted price of 10/1 on a horse whose standard price is 7/1, BOG may not apply to the boosted element.
Finally, BOG is predominantly a UK and Irish racing feature. International fixtures — French racing, Australian carnival meetings, US stakes races — are rarely covered unless the bookmaker explicitly states otherwise. None of these limitations diminish the value of the promotion; they simply define its boundaries. The best of both prices remains the best of both prices — you just need to know where the fences are.
