Horse racing is an equestrian sport that has been practiced over the centuries; the chariot races of Roman times are an early example, as is the contest of the steeds of the god Odin and the giant Hrungnir in Norse mythology. It is often inextricably associated with gambling. The common nickname for Thoroughbred horse racing is The Sport of Kings.
One of the principal forms of horse racing, which is popular in many parts of the world, is Thoroughbred racing. Harness racing is also popular in the eastern United States and more popular than Thoroughbred racing in Canada and parts of Europe. Quarter horse racing is also popular in the western United States and Florida. Racing with purebred Arabian horses exists in several states in the United States, as well as in most of Europe and the Middle East.
