bareback bronc-riding
bareback bronc-riding, rodeo event in which a cowboy or cowgirl attempts to ride a bucking horse (bronco) for eight seconds. The horse is equipped with a leather and rawhide handhold āriggingā cinched on like a saddle. The rider grasps the rigging with only one hand, and the holding arm absorbs most of the horseās bucking power. At the beginning of the event, the rider is required to āmark outā; that is, the contestantās spurs must be touching a point high on the horseās shoulders before the animalās front feet first hit the ground after it leaves the chute; this gives the horse the initial advantage. Disqualification occurs if the rider touches the horse or any part of the riderās own body or equipment with the free hand, fails to āmark out,ā or is bucked off before the whistle. Horse and rider are scored separately for their performance, and the rider with the highest total wins.
