Many Clouds, ridden by Leighton Aspell, has powered to victory in the 2015 Grand National at Aintree.
The 25-1 shot held off a strong challenge from Saint Are as Aspell recorded back-to-back victories in the race after winning in 2014 on Pineau Du Re.
Aspell told Channel 4: "Wonderful. Absolutely wonderful. He gave his all. I tried to conserve energy but what a wonderful run. It's the best ride I've had over these fences."
19-time champion jockey Tony McCoy, who will retire at the end of the season, was in contention throughout the race but after going over the final fence in third on Shutthefrontdoor, he faded badly to eventually finish in fifth.
Third place was taken by Monbeg Dude while Alvarado finished strongly to edge ahead of McCoy's ride.
