Nico de Boinville celebrates after piloting Sprinter Sacre to a sensational win in the Champion Chase
Sprinter Sacre, trained by Nicky Henderson and ridden by Nico de Boinville, won the Betway Queen Mother Champion Chase, the highlight on day two of the Cheltenham Festival.
Invincible when imperious in this race three years ago, Sprinter Sacre has had a succession of well-documented problems but has been brought back by his trainer Nicky Henderson to be the top two-miler again.
Sprinter Sacre (5-1) surged past a tame Un De Sceaux two out and pulled clear under Nico de Boinville to bring a packed house down at Prestbury Park.
Un De Sceaux, the 4-6 favourite, was still second best, beaten three and a half lengths behind the popular winner after being unable to dominate in his usual manner.
The pace had been set by Special Tiara (16-1), who was just a nose behind Un De Sceaux in third.
Henderson said: "It's been a long, long journey – those were two very, very grim years.
"That was unbelievable. That was about dreams, wasn't it?"
