Lion Na Bearnai provided trainer Tom Gibney and jockey Andrew Thornton with the biggest success of their careers in the Ladbrokes Irish Grand National at Fairyhouse this afternoon.
A surprise winner of the Ten Up Novice Chase at Navan, the 10-year-old showed stamina in abundance to see off Edward O'Grady's Out Now after the last fence.
Gibney trains only a handful of horses near the track and Thornton is a 3lb claimer, proving that the big races can still be won by the smaller yards.
The winner returned at 33-1 and won by four and a half lengths. Jonjo O'Neill's Alfie Sherrin ran another good race in third, with Paddy Pub fourth.
