C. FOINAVON

Aintree's trick is compounded when the seventh fence comes very quickly after the shock at Becher's.

It is named the Foinavon fence after the hero of the 1967 race when only he scrambled over it at the first time of asking following a mass pile-up.

The jump is the smallest on the course, but coming straight after the biggest drop, it can catch cocky horses and riders out.
