I Am Maximus has finished first and second in his two runs in the Grand National
I Am Maximus, the 2024 winner, will attempt to win his second Grand National at Aintree on Saturday.
I Am Maximus, owned by JP McManus, triumphed by seven-and-a-half lengths two years ago then finished two-and-a-half lengths behind Nick Rockett - trained by Willie Mullins and ridden by his son Patrick - in 2025.
Jockey Paul Townend has stuck with I Am Maximus for the third successive year, while Nick Rockett was declared a non-runner on Thursday morning after being reported to be coughing.
Willie Mullins is looking to become the first trainer to win the race in three successive years since Vincent O'Brien between 1953 and 1955.
Panic Attack, trained by Dan Skelton, is vying with I Am Maximus for favouritism as she looks to become the first mare to win the race in 75 years.
The maximum field of 34 will run, with reserves Imperial Saint and Amirite completing the line-up after Nick Rockett and Spillane's Tower were withdrawn.
Saturday 11 April, 16:00 BST

Dan Skelton will be represented by Panic Attack as he closes in on the British trainers' championship for the first time.
The Nigel and Willy Twiston-Davies-trained Beauport will carry the colours of Bryan and Philippa Burrough, for whom Corbiere won in 1983 as Jenny Pitman became the first female trainer to triumph.
Nigel is a two-time winner of the race in 1998 and 2022 and the stable are also set to saddle Top of the Bill, who moved into the top 34 with Monday's withdrawals.

How the Grand National has changed
Organisers introduced a series of new safety measures in 2024 for the Grand National.
As well as reducing the line-up, there is a shorter run to the first fence to slow horses down and a reduction in height to one of the fences. A standing start was reintroduced along with further veterinary checks.
The National time was brought forward an hour and 15 minutes to reduce the build-up and provide safer ground for runners in case of drying conditions.
In 2024 there were no fallers and 21 horses completed the race - the highest number across the finish line since 1992 - with four horses unseating their riders and seven pulled up.
Last year saw 16 finishers, three fallers, 13 pulled up, one horse was brought down and one unseated their rider.
