Who is the betting favourite to win the 2026 Grand National at Aintree?
The 2026 Randox Grand National is finally here, the big race takes place tomorrow at 16:00.
The finally field has been confirmed and the 34 runners are ready to thunder out onto Aintree, tackling 30 fences across 4 miles 2½ furlongs, in a test that blends stamina, precision jumping and will power.
This year’s renewal has already produced drama before the tapes have even gone up. Nick Rockett, last year’s winner, was withdrawn just 48 hours before the race due to a cough.
I Am Maximus, the 2024 champion and last year’s runner‑up, is the headline act. The Willie Mullins-trained star now attempts to become only the eighth dual winner in Grand National history, carrying top weight of 11st 12lb as he bids to reclaim the crown. He heads a field stacked with depth: Grangeclare West, Jagwar, Banbridge, Gerri Colombe, Monty’s Star, and a host of seasoned stayers and rising chasers all taking their chance

Who is the Grand National 2026 Favourite to Win?
The front of the Grand National market is shaped by a mix of proven course form and upwardly mobile profiles, with I Am Maximus (8/1) setting the standard as last year’s winner who arrives in even better form, having placed in both the Savills Chase and run respectably in the Irish Gold Cup, while retaining the partnership of Paul Townend.
Close behind in the betting, Grangeclare West (10/1) has strong claims of his own after finishing a close third in this race last year, where a late mistake arguably cost him victory, and his dominant Bobbyjo Chase win over Gerri Colombe highlights both class and stamina, even if he has been overlooked by Townend.

Jagwar (11/1) represents the progressive angle, with consistent form over fences and a near-miss in the Ultima suggesting he stays the trip well enough, though his jumping under pressure remains a key concern over these fences.
Meanwhile, Panic Attack (8/1) adds further depth as an improving mare who has already held her own in major handicaps and arrives off a solid Cheltenham run, with the extended trip expected to bring out further improvement. Together, these leading contenders combine strong recent form, proven stamina, and, in some cases, valuable experience of the unique demands of Aintree.
