The Breeders’ Cup World Championships is an annual series of Grade I Thoroughbred horse races, operated by Breeders’ Cup Limited, a company formed in 1982. From its inception in 1984 through 2006, it was a single-day event; starting in 2007, it expanded to two days. All sites have been in the United States, except in 1996, when the races were at the Woodbine Racetrack in Canada.
Each Breeders’ Cup race presents four Breeders’ Cup trophies to the connections of the winner and a garland of flowers draped over the withers of the winning horse. Many Breeders’ Cup winners will go on to win the Eclipse Award in their respective division. For example, of the eleven flat racehorse categories, seven of the Eclipse winners in 2015 had also won a Breeders’ Cup race, while three others were in the money.
