One of the sensational finishes to a Grand National took place 46 years ago, when complete outside Foinavon snatch a remarkable 100/1 victory.
The rank outsider galloped to an unforgettable win in 1967 after being the only horse to avoid a huge melee at the 23rd fence and clear it first time.
A pile-up started by loose horse Popham Down saw at least seven horses collide, allowing Foinavon to dodge the chaos, leap the fence and build an unexpected lead of 30 lengths.
Rutherfords, Rondetto, Norther, Kirtle Lad, Princeful and Leedsy were among the horses caught up in the pile-up, which effectively brought the race to a halt.
Foinavon was such an outside before the race that his owner went to Worcester on race day instead.
In the end though, his slow pace worked in his favour, as he was so far behind when the pile-up happened that his jockey, John Buckingham, had enough time to veer wide of the carnage, navigate towards a gap in the fence, and leap ahead on the outside.
After the crash 17 jockeys remounted and made up some ground on Foinavon, but ran out of time before the outsider, 'with the biggest odds in 20 years', came home 15 lengths clear.
