Brief History

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.

Important races
The high point of US horse racing has traditionally been the Kentucky Derby which, together with the Preakness Stakes and the Belmont Stakes, form the Triple Crown of Thoroughbred Racing for three-year-olds. However, in recent years the Breeders' Cup races, held at the end of the year, have been challenging the Triple Crown events, held early in the year, as determiners of the three-year-old Champion. The Breeders' Cup is held at a different track every year; the most recent edition (2007) was held at Monmouth Park. It also has an important effect on the selection of other annual Champions. The corresponding Standardbred event is the Breeders' Crown. There are also a Triple Crown of Harness Racing for Pacers and a Triple Crown of Harness Racing for Trotters.
