When Every Favourite Falls Short
In 2025, all four championship race favourites at Cheltenham Festival were beaten. Constitution Hill, the Champion Hurdle banker. The Champion Chase market leader. The Stayers’ Hurdle and Gold Cup principals. All defeated. Bookmakers were spared an estimated £50 million in Day 1 payouts alone. Punters who stacked their Festival strategy around backing favourites walked away with empty pockets and the same question they ask every March: what went wrong?
The answer is structural, not accidental. Cheltenham Festival is the one week of the year where the favourite’s strike rate drops furthest below what the odds imply. The unique combination of elite-level competition, unpredictable going conditions, and the emotional pressure of the occasion creates an environment where market leaders underperform their probability more frequently than at any comparable meeting. Value betting — identifying horses whose odds overstate their losing chance — is not just an alternative strategy at Cheltenham. It is the appropriate response to a data set that punishes favourite-backers year after year. Favourites fall — be ready.

The Data: How Often Do Cheltenham Favourites Win?
The historical record is unambiguous. In championship races at Cheltenham — the Champion Hurdle, Champion Chase, Stayers’ Hurdle, and Gold Cup — the favourite wins at a rate of approximately 35–40% across the last two decades. That is a reasonable strike rate in absolute terms, but it falls short of what the odds imply. A horse sent off at 6/4 carries an implied probability of 40%. If favourites at these prices won 40% of the time, backing them would break even (before overround). In practice, the championship favourite wins closer to 35%, creating a consistent negative expectation for the favourite-backer.
In handicap races, the picture is starker. The big Cheltenham handicaps — County Hurdle, Coral Cup, Grand Annual, Pertemps Final — feature fields of 16 to 24 runners where the favourite’s strike rate drops below 15%. These are races designed to produce competitive finishes, and the sheer number of runners means any single horse’s chance of winning is inherently low. Backing the favourite in a 20-runner handicap at 5/1 (implied probability 17%) when the true strike rate is 12–15% is a losing proposition over any meaningful sample.
The 2025 Festival crystallised this pattern in extreme form. Four championship favourites beaten is unusual — the expected rate over a four-race sample is approximately one or two losing favourites, not four. But the fact that it can happen, and does happen periodically, illustrates why building a Festival strategy around favourites is fragile. A strategy that fails catastrophically one year in five is not robust, regardless of how comfortable it feels in the other four years.
The levy yield from horserace betting hit a record £108.9 million in FY2024/25, driven partly by bookmaker-friendly Festival results. Record levy yields mean bookmaker margins are growing, which means odds are tighter, which means the value available on favourites is shrinking further. When bookmakers are earning more per pound wagered, the price you get on any selection — including the favourite — represents worse value than it would in a more competitive margin environment.
Identifying Value: Price vs Probability
Value exists when the odds offered on a selection overstate its losing probability. If a horse has a true 25% chance of winning and the bookmaker offers 5/1 (implied probability 17%), the bet has positive expected value. You are being paid as though the horse has a 17% chance when it actually has a 25% chance. Over time, making these bets consistently produces profit.
Identifying true probability at Cheltenham requires the same analytical tools used in any form analysis — recent form, course form, going preferences, trainer statistics at the Festival, jockey booking patterns — combined with the recognition that the market itself is not always efficient. The Cheltenham market is influenced by sentiment, media narratives, and the weight of public money on popular horses. These factors can push favourites to shorter prices than the form justifies, creating value elsewhere in the market.
One practical method: after completing your form analysis for a race, estimate each horse’s win probability as a percentage. Then compare your estimates to the bookmaker’s implied probabilities (derived from the odds). Where your estimate is significantly higher than the bookmaker’s — by 5 percentage points or more — you have identified a potential value bet. Where your estimate matches the bookmaker’s, the price is fair. Where the bookmaker’s implied probability is higher than your estimate, the horse is overpriced in your model and should be avoided.
This approach does not require mathematical sophistication. If you believe a horse has roughly a one-in-four chance and the odds say one-in-six, you have found value. The discipline is in sticking to your analysis when the market disagrees, and accepting that value bets lose more often than they win — the profit comes from the occasions when they do win at prices that overcompensate for the losing runs.
Each-Way as a Value Strategy
Each-way betting is the natural companion to value betting at Cheltenham. If you have identified a horse with a better chance than the market implies, backing it each-way extends the range of profitable outcomes. The horse does not need to win — it needs to finish in the places. At a festival where favourites fail regularly, horses that run well without winning produce the most consistent each-way returns.
The value of each-way as a strategy is amplified by extra-place offers on the big handicaps. If a bookmaker pays 6 places instead of 4 on the County Hurdle, your value selection at 12/1 now collects if it finishes anywhere in the first six. The underlying value thesis — this horse is better than the market thinks — only needs to hold partially: the horse does not need to prove you completely right by winning. It needs to prove you roughly right by running into the places.
Pairing value each-way bets with BOG adds another layer. If you take an early morning price on a value selection and the market subsequently drifts (as it often does for horses that are not the public’s favourite), BOG captures the higher SP. Your value analysis led you to the horse, the odds led you to each-way, and BOG led you to the early morning price. Each element reinforces the others.
Lessons from 2025: What the Upset Festival Teaches
The 2025 Cheltenham Festival was not a random outlier. It was an extreme expression of patterns that recur annually in milder form. The specific lessons are worth building into your 2026 strategy.
Lesson one: the deeper the favourite’s price, the more fragile the bet. Constitution Hill was odds-on for the 2025 Champion Hurdle. At that price, the expected return from backing the favourite was already thin — the risk-reward ratio offered almost no margin for error. When errors occurred (as they inevitably do in jump racing), the entire investment was lost. A value-focused punter who backed the Champion Hurdle winner at 10/1 or 12/1 earned a transformative return from the same race. The favourite-backer earned nothing.
Lesson two: offers should have been the safety net. Punters who backed Constitution Hill each-way still collected the place portion if the horse finished in the places. Those who used money-back-if-second promotions received refunds on near-misses. Those with BOG captured any price drift. The punters who suffered most were those who backed the favourite to win outright with no promotional support — the maximum-risk, minimum-protection approach. Offers do not change the outcome of a race, but they change the financial consequence of being wrong.
Lesson three: the value was available before the race started. In every championship race of the 2025 Festival, the eventual winner was available at generous odds ante-post and on the morning of the race. The form was there. The market simply underestimated those horses because the favourite dominated the narrative. Punters who did their own analysis, rather than following the crowd, identified value that the market overlooked. That is the repeatable principle for 2026: do the work, find the price, trust your assessment, and let the offers protect the downside.

Handling Variance Without Chasing Losses
Value betting is a long-term strategy with short-term variance. You will have losing days and losing festivals. The maths works over hundreds of bets, not single events. Do not increase your stakes to recover a losing streak, and do not abandon the approach after one bad result. If the variance becomes stressful, reduce your stakes or take a break.
