Becher's Brook (/ˈbiːtʃərz/ BEECH-ərz) is a fence jumped during the Grand National, a National Hunt horse race held annually at Aintree Racecourse near Liverpool, England. It is jumped twice during the race, as the sixth and 22nd fence, as well as on four other occasions during the year. It has always been a notorious and controversial obstacle, because of the size and angle of the 6 ft 9in drop on the landing side. Some jockeys have compared it to "jumping off the edge of the world."
After the deaths of Dark Ivy in the 1987 Grand National and Seeandem and Brown Trix in the 1989 Grand National, all at Becher's Brook, Aintree bowed to pressure from animal rights groups and undertook extensive modifications to the fence. Further changes were made after two horses, Ornais and Dooneys Gate, died during the 2011 Grand National, the latter at Becher's. The incident involving Dooneys Gate resulted in the fence being jumped only once for the first time in the race's history; it was bypassed on the outside on the second circuit while veterinary staff attended to him.
The fence took its name from Captain Martin Becher, who fell there from his mount, Conrad, in the first official Grand National in 1839, and took shelter in the brook to avoid injury. The jump originally consisted of an 8 ft-wide brook with a fence set back a yard in front of the water, the ground on the landing side 3 ft lower than the take-off side.
