Uses

Although the Thoroughbred is primarily bred for racing, the breed is also used for show jumping and combined training because of its athleticism, and many retired and retrained race horses become fine family riding horses, dressage horses, and youth show horses. The larger horses are sought for hunter/jumper and dressage competitions, whereas the smaller horses are in demand as polo ponies.
