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.
