Grey Abbey outjumped his rivals for an outstanding victory in the Betfair Bowl Chase at Aintree on Thursday.
The Howard Johnson-trained horse, a 7-2 shot ridden by Graham Lee, cruised clear of First Gold, with Crystal d'Ainay finishing back in third.
Grey Abbey had been earmarked for retirement but will now race on.
Martin Pipe's main contender Our Vic was never travelling well in the feature race on the Grand National meeting's opening day.
Grey Abbey, who was fifth behind Kicking King in the Cheltenham Gold Cup last month, may now be aimed at the Scottish Grand National.
Johnson had thought about retiring the horse after he suffered a recurring joint problem, but owner Norman Furness revealed the fresh plan.
"He's going to stay in training next year and he will probably go for the Scottish National (on Saturday week) depending on how he comes out of the race," said Furness.
"We were expecting a good run but you never know what's going to happen in a race like that."
Later, 100-30 favourite Katarino - ridden by Sam Waley-Cohen for his owner-trainer father Robert - won the Fox Hunters' Chase over the National fences.
Caught at Dawn (25-1) was second and Montifault (7-1) third.
Several leading contenders fell and former Triumph Hurdle winner Katarino survived a bad mistake at the Canal Turn.
