Sam Waley-Cohen is hoping Long Run's class will come to the fore when he lines up in the Crabbie's Grand National on April 5.
The 2011 Cheltenham Gold Cup winner is set to tackle the unique Aintree fences for the first time after failing to hit his usual heights so far this term.
Well beaten in two initial starts, he unshipped Waley-Cohen in the King George on Boxing Day but bounced back to winning form when dropped in class at Kelso last month.
Waley-Cohen told Channel 4's The Morning Line: "We're very happy with him. In many ways the season hasn't gone to plan, but we went to Kelso and that was a great confidence-boosting run.
