A supercomputer has predicted the winners from day one of the 2025 Cheltenham Festival, which gets underway on Tuesday.
Using data going all the way back to 1990, the machine has analysed every winning horse at Cheltenham while including a variety of factors such as age, betting position, past results and trainer records.
An algorithm then attributes a score of between 1 and -1 depending on how well each horse matches the winning characteristics.
The characteristics are then used to identify the horses most likely to win each race at this year’s festival – but it is bad news for favourites.
Tuesday’s top race sees Constitution Hill (8/11) as the favourite listed in Tuesday’s feature race – the Champion Hurdle.
While the eight-year-old missed the 2024 edition of the festival, it beat Lossiemouth at Kempton in January and remains unbeaten with eight Grade One victories.

In another of the first day’s top races – the Arkle Challenge Trophy Novices’ Chase – Majborough has also been tipped for victory.
Anyone looking to back an outside may be best placed hedging their bets on the Supreme Novices’ Hurdle, which is scheduled to get underway at 1:20pm on Tuesday afternoon.
At 12/1, Workhead has been predicted to beat odds-on favourite Kopek Des Bordes (5/6) in the first race of the day.
The supercomputer also predicts that Crebilly will beat The Ultima Handicap Chase favourite The Changing Man, which is pencilled in for 2:40pm.
However, the biggest upset could come in the Mares Hurdle, with the algorithm predicting champion Lossiemouth at 4/5 to lose out to Jade De Grugy at 5/2.
Lossiemouth is also due to race against overwhelming favourite Constitution Hill in the Champion Hurdle at 4:00pm in the day’s headline race.
