Jonjo O'Neill intends to plan Shutthefrontdoor's campaign round a crack at the Crabbie's Grand National at Aintree in April.
The seven-year-old, who took the Irish Grand National at Fairyhouse in April, is likely to make his reappearance in the Weatherbys Hamilton Insurance Graduation Chase over an extended three miles at Carlisle on 10 November.
"We'll probably start him off in a race at Carlisle for horses that have won a couple of race on November 10," O'Neill told At The Races.
"We'll see how he is, see what form he is in and then look at the long-distance races.
"I would say he's a National horse. That's the way I see him at the moment.
"He's one we'll be shaping that way and hopefully he'll be good enough to go for it.
"He's not a fast horse, he's a galloper and, touch wood, he's a reasonably good jumper.
"If he gets into to a nice rhythm round there (Aintree) it would suit him well, so that's where I would like to end up with him."
