Developed from the early chore of breaking wild horses, ranch hands would often gather and compete to see who could ride wild horses with the most style.
The rider must begin the ride with his feet over the bronc's shoulders or risk a "no score." During the ride the cowboy must synchronize his spurring action with the animal's bucking efforts. Model spurring action begins with the rider's feet on the bronc's point of shoulder, sweeping to the back of the saddle ad the horse bucks and is repeated during the ride. The rider also uses a buck rein for balance.
The rider is disqualified if he touches the animal, himself or his saddle with his free hand, if either foot slips out of a stirrup or if he drops the bronc rein during the eight-second ride.
