A jockey is someone who rides horses in horse racing or steeplechase racing, primarily as a profession. The word also applies to camel riders in camel racing. The word "jockey" originated from England and was used to describe the individual who rode horses in racing. They must be light, typically around a weight of 100–120 lb., and physically fit. They are typically self-employed, and are paid a small fee from the horse trainer and a percentage of the horse's winnings. The job has a very high risk of debilitating or life-threatening injuries.

The Breeders' Stakes is a stakes race for Thoroughbred race horses foaled in Canada, first run in 1889. Since 1959, it has been the third race in the Canadian Triple Crown for three-year-olds. Held annually in October at Woodbine Racetrack in Toronto, Ontario, the Breeders' Stakes follows the August running of the King's Plate and the September running of the Prince of Wales Stakes. At a distance of one-and-a-half miles, the Breeders' Stakes is the longest of the three Triple Crown races and is the only jewel raced on turf.
