A feisty calf that runs fast or kicks hard can foil a roper's finest effort. At Cheyenne, the calf is given a 30-foot head start before horse and rider can legally give chase, which is signaled by a judge on the ground. If the calf is not standing when the contestant reaches it, the cowboy must get the animal to its feet, then flank it. Leaving the box early results in the cowboy receiving a 10-second penalty. Tightly strapped spurs, a well-rosined leather riding glove, and chaps are the balance of equipment brought to the fray by the rider.
Riders attempt to stay seated close up on the rope handhold, legs slightly forward.
Slipping back off the rope will cause the bull's power to jerk the cowboy's hand loose and launch him into next week. Spinning bulls are considered more hazardous to ride and usually score higher. Bareback riders must have an incredible sense of balance and timing, as well as extraordinary upper body strength. Horses that make outstanding bareback broncs are usually smaller than average, being lean and quick. Horses are scored for the power that they generate in bucking, with added points for high kicking, changes in direction, and quickness.
