Mullins Duo Add Historic Angle to 2026 Renewal

The 2026 Grand National is shaping up to be a fascinating renewal, with the last two winners of the race, I Am Maximus and Nick Rockett, both confirmed for Saturday’s showpiece at Aintree.

Trained by Willie Mullins, the pair have dominated recent editions:

  • I Am Maximus stormed to victory in 2024, winning by seven and a half lengths
  • Nick Rockett followed up in 2025, scoring under Patrick Mullins

Interestingly, I Am Maximus finished two and a half lengths behind Nick Rockett last year, adding another layer of intrigue to their rivalry heading into 2026.

Both horses now top the weights, as Mullins bids for a remarkable hat-trick of Grand National victories.

Now attention turns to the betting odds on the big race of the weekend, with bookmakers offering markets ahead of Saturday's main event.

I Am Maximus Leads Mullins Charge

I Am Maximus heads the betting at 7/1, with strong support reflecting both his previous victory and consistent profile over staying trips.

Owned by JP McManus, his dominant 2024 success still stands out as one of the most impressive recent National performances.

However, with top weight to carry and a strong field behind him, a repeat success will be far from straightforward.

Nick Rockett Adds Champion Credentials

Last year’s winner Nick Rockett is priced at 16/1, offering each-way appeal given his proven ability over the Aintree fences.

His victory under Patrick Mullins in 2025 demonstrated both stamina and composure, which are key attributes for success in this race.

The fact he beat I Am Maximus last year adds extra intrigue, particularly for those looking beyond the favourite.

What the expert says...
Having the last two winners in the field, both from the same yard, is a huge storyline. But with top weights and a deep field, this is still a very open National.
