The most notorious jump in horse racing, Becher's brook is part of the most demanding steeplechase on earth, the (British) Grand National at Aintree. The jump actually has to be negotiated twice during the race – as the sixth and twenty-second fences.
It takes its name from Captain Becher, who famously took refuge in the small brook running on the landing side of the fence. This was during the very first Grand National, when he was unseated by his horse, Conrad. The brook is now concealed under a line of cast iron drain covers.
