At the NRCHA Celebration of Champions, the NRCHA World Championship Show, top horses and riders from each of the NRCHA’s eight geographic regions competing for World Championship titles in twelve exciting events. In the World’s Greatest Horseman, it is all about one horse, one rider and one very impressive title. In one bit, horses compete in four contests: herd work, rein work, steer stopping and cow work. The NRCHA Celebration of Champions also includes Celebration of Champions Derby for 4- and 5-year-old cow horses.
