Many of us will like to have a flutter today as The Grand National at Aintree, the highlight of the British horse racing calendar is among us today.
With 34 runners, picking the winner can be something of a lottery, but can a Supercomputer predict the outcome?
The model, conducted by BOYLE Sports, has projected a win probability for Panic Attack of 15.1% and will bag glory by two-and-a-half lengths from the Willie Mullins-trained Grangeclare West in second, who has been predicted an 11.8% victory chance.
I Am Maximus, the winner of the race in 2024 and runner-up last year, is projected to finish in third this year, completing a second and third place finish for powerful trainer Mullins. The ten-year-old, who will carry top weight in this year’s race, has been handed an 11.2% chance of winning but will finish a neck behind Grangeclare West according to the model from the bookmaker, who offer the latest Grand National odds.
The Supercomputer has projected that Haiti Couleurs, a previous winner of the Welsh and Irish Grand Nationals, ridden by Carmarthenshire jockey Sean Bowen, will come home in fourth and has a 9.4% chance of victory, while Oscar’s Brother, for trainer Connor King, will come home in fifth.
Two Oliver Greenall and Josh Guerreiro-trained runners, Jagwar and Iroko, will finish in sixth and seventh respectively according to the projection.
Overall, the model predicted 21 runners will complete the race this year, with The Real Whacker being the last finisher.
Supercomputer Methodology Note
The standings were generated using a multi-factor simulation model:
- Form & Stamina Index: It analysed seasonal performance (e.g., Panic Attack’s Coral Gold Cup win) against the grueling 4m 2f trip. Horses like Haiti Couleurs (Welsh National winner) received a high “stamina rating.”
- Weight-to-Probability Ratio: I Am Maximus carries top weight (11st 12lb). Historical data suggests a significant speed decay over the final 4 furlongs for top weights, which influenced his 3rd-place prediction despite being the class favorite.
- Jockey/Trainer “Micro-Form”: Simulations gave weight to the Skelton/Skelton partnership’s recent strike rate and Willie Mullins’ historical dominance (4 of the top 13 predicted finishers).
- Attrition Modeling: Grand National historical completion rates (approx. 50-60%) were applied to simulate falls (UR/F) and pull-ups (PU). Banbridge and Firefox were modeled as high-risk finishers due to stamina doubts at the distance.
- Data Sources: This model synthesized data from Racing Post (field declarations), Oddschecker (market sentiment), and Timeform (weight-adjusted ratings).
Final Analysis Summary: The Supercomputer favours Panic Attack to provide Dan Skelton with a historic win, outstaying Grangeclare West on the run-in. Last year’s winner I Am Maximus is predicted to run a heroic race under top weight but find the concession of nearly 20lbs to the winner too much in the final 100 yards.
