The Grand National is a National Hunt horse race held annually at Aintree Racecourse, Aintree, Merseyside, England. First run in 1839, it is a handicap steeplechase over an official distance of about 4 miles and 2½ furlongs, with horses jumping 30 fences over two laps. It is the most valuable jump race in Europe, with a prize fund of £1 million in 2017. An event that is prominent in British culture, the race is popular amongst many people who do not normally watch or bet on horse racing at other times of the year.

Horse racing is an equestrian performance sport, typically involving two or more horses ridden by jockeys over a set distance for competition. It is one of the most ancient of all sports, as its basic premise – to identify which of two or more horses is the fastest over a set course or distance – has been mostly unchanged since at least classical antiquity.
