Best Odds Guaranteed at Cheltenham 2026: Which Bookmakers Honour It and When

The Price You Take Is Not Always the Price You Get Paid

I backed a 12/1 shot in the 2023 Supreme Novices’ Hurdle at nine o’clock on Tuesday morning. By the time the race went off, the starting price had drifted to 16/1. Because I had placed the bet with a firm running Best Odds Guaranteed, I was paid at 16/1 – an extra £40 on a £10 stake for doing absolutely nothing except choosing the right bookmaker. That single experience converted me into someone who checks BOG policies before anything else during festival week.

Best Odds Guaranteed – BOG – is a promise from the bookmaker that if the starting price of your horse is higher than the price you took, you will be paid at the better number. It costs you nothing. It applies automatically where offered. And at Cheltenham, where early prices can shift dramatically between morning and post time across all 28 races, it is one of the most underappreciated sources of free value in the entire betting calendar. William Hill projects approximately £450 million in wagers across the four Festival days, and a meaningful proportion of that money is placed at early prices that could be improved by BOG.

The catch, as always, is in the fine print. Not every firm offers it. Not every firm that offers it applies it to every market. And the limits and exceptions vary enough to make blanket assumptions dangerous.

How Best Odds Guaranteed Works on Festival Day

Picture the morning of Gold Cup Friday. You fancy a horse at 8/1. You place your bet at 8am. Over the next five hours, money pours in for another runner, your horse drifts to 10/1 in the market, and the starting price is officially returned at 10/1. With BOG, you are paid at 10/1. Without it, you are stuck at 8/1.

The mechanism works only in one direction. If you take 8/1 and the starting price contracts to 5/1, you still get your 8/1 – BOG does not punish you for taking an early price that turns out to be generous. It is a one-way ratchet that always favours the punter. The settlement happens automatically at most firms; you do not need to claim it or contact support.

BOG typically applies to win and each-way bets on UK and Irish horse racing. At Cheltenham, that covers the entire Festival card. It usually kicks in from the moment early prices are posted – often the morning of the race – and runs until the off. Some firms extend it to bets placed the evening before, which is useful if you prefer to get your positions in without the distraction of morning market noise.

Where it gets nuanced is the interaction with other offers. If you place a free bet token on a selection that triggers BOG, most firms will apply BOG to the free bet just as they would to a cash stake. That is a compounding benefit: you are already getting an enhanced return from the token, and BOG potentially increases it further. I have had tokens pay out at prices 20-30% above what I originally clicked, simply because the SP drifted.

BOG Policies Compared: Limits, Exceptions and Exclusions

Three years ago, BOG was essentially universal among major UK bookmakers. That is no longer the case, and the divergence in policies is worth understanding before you lock in a Cheltenham bet.

The most significant variable is the stake limit. Some operators cap BOG at a maximum stake of £500 or £1,000, meaning any amount above that threshold is paid at your original price even if the SP was higher. For most casual festival punters, these caps are irrelevant. For anyone placing three-figure stakes on feature races, they matter enormously. A £200 bet on a horse that drifts from 6/1 to 10/1 is worth an extra £800 with BOG – but only if the firm honours the policy at that stake level.

The second variable is market scope. Some firms restrict BOG to day-of-race betting only, excluding ante-post wagers. Others apply it from the moment early prices go up, which can be several days before the race. At Cheltenham, where the ante-post market is unusually active, this distinction is especially relevant. If you placed an ante-post bet six weeks ago, BOG will not cover it at most firms even if the SP on race day is significantly higher. HBLB’s levy yield hit £108.9 million last year, the highest since the 2017 reforms, partly because of the volume of early-market trading around events like Cheltenham – and punters taking early prices without BOG protection accounted for a portion of that bookmaker-friendly margin.

A third consideration is whether the firm suspends BOG during the Festival itself. This happened with a couple of operators in recent years, usually justified by the volume of promotional activity already running. If your chosen firm withdraws BOG for Cheltenham week, you lose the safety net at precisely the moment it has the most value. It is worth checking in the days before the Festival, not on the morning of the first race.

Races Where BOG Makes the Biggest Difference

Not all Cheltenham races produce the same scale of price movement. The feature championship races – Gold Cup, Champion Hurdle, Queen Mother Champion Chase, Stayers’ Hurdle – tend to have smaller fields and more predictable markets. Prices shift, but the magnitude is often modest: a point or two of drift rather than wholesale market reshuffles.

The big handicaps are a different animal. The Coral Cup, the County Hurdle, the Grand Annual and the Martin Pipe – these races regularly feature fields of 20 or more runners, and the morning market can look nothing like the SP board. Late money, non-runners reshaping the market, jockey bookings confirmed after declarations – all of these factors create price volatility that BOG converts into free upside for early backers.

I have found that the best use of BOG at Cheltenham is to take early-morning prices on handicap runners that I expect to drift. If the horse has a profile that suggests it will not attract late support – unfashionable trainer, moderate recent form, long price already – there is a reasonable chance the SP will be even bigger than the morning number. With BOG, you are guaranteed to be paid at the larger figure if it materialises. Without it, you are simply stuck with whatever you clicked at breakfast.
