The 1967 Grand National saw its most notorious pile up in history and Foinavon who had odds of 100/1 to win the race won. Even the horse's owner Cyril Watkins didn't bother to attend Aintree because the chances of a win were wholly improbable.
As expected, Foinavon did not play a competitive part in the race until at the 23rd fence, a loose horse cut across the riders causing all other horses to either fall, unseat their riders or refuse to jump. Foinavon and his rider, John Buckingham, were so far behind that they managed to bypass the shambles, jump the fence and take a lead of 200 yards.
Although most riders were able to remount, no one managed to quite catch up with horse and rider. Luckily nobody died in the accident.
