Bareback riding offers a sensation about as enjoyable as riding a jackhammer, pogo stick-style, using only one hand. Bareback riding is the most physically demanding event in rodeo, its toll on the body is immense. The strength of the broncs is exceptional and challenging them is often costly. Bareback riders endure more punishment, suffer more injuries and carry away more long-term damage than all other rodeo cowboys. To stay aboard the horse, a bareback rider uses a rigging made of leather and constructed to meet PRCA Rodeo safety specifications. As the bronc and rider burst from the chute, the rider has to mark out his horse. If the cowboy fails to do this, he is disqualified.
