A punter saw their £40,000 bet go up in smoke when Galopin Des Champs fell at the last fence when well clear of the field in the opening race on day three of the Cheltenham Festival.
The Willie Mullins-trained Galopin Des Champs - the 5/6 fav - had pulled well clear with a tenacious jumping display until the final jump, over jumped at that point and skidded to the ground to a terrible groan from the Cheltenham crowd.
That left Bob Olinger and Rachael Blackmore to ride home to victory.
