J.P McManus is now the most successful Grand National owner of all-time following I Am Maximus' victory in the 2026 race.
9/2 favourite I Am Maximus has won his second Grand National after previously winning in 2024 and he is just the eighth horse to win two Grand Nationals.
J.P McManus had his first winner in the race in 2010 when Tony McCoy guided 10/1 joint-favourite Don't Push It home to also secure his first win in the process.
An 11-year wait followed before Minella Times landed the 2021 Grand National, with Rachael Blackmore becoming the first female jockey to win the race.
The two wins for I Am Maximus have helped to move McManus to the top of the list and he is now one clear of five different ownerships.
