The Grand National, the biggest event in horse racing, features a difficult track that can prove challenging for participants.
The Grand National is one of the highlights of the UK horse racing calendar, with a total prize pot of £1million on offer.
The triangular course, at Aintree Racecourse, has 16 fence jumps topped with spruce branches from the Lake District. Competitors are required to jump the first 14 twice before racing down the run-in to cross the finish line.
