Colm Murphy is convinced Quito De La Roque's fortitude could stand him in good stead for the Crabbie's Grand National at Aintree on Saturday.
The Grade One-winning 10-year-old has had a disappointing season - he was pulled up on his last outing at Fairyhouse in February - but the County Wexford handler is not without optimism.
Quito De La Roque shaped encouragingly in two previous starts at Aintree, most significantly when he won the Mildmay Novices' Chase in 2011.
Murphy said: "He's going along nicely at home.
"He's had his problems over the years but he's a tough horse, which is obviously important in the National.
"We're very happy with him and his preparation has gone well."
