Ascot Racecourse is a dual-purpose British racecourse, located in Ascot, Berkshire, England, about 25 miles west of London. Ascot is used for thoroughbred horse racing, and it hosts 13 of Britain's 36 annual Flat Group 1 horse races and three Grade 1 Jumps races.

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.
