Bull-riding event is a type of RODEO, which is an event that originated in the United States in the late 19th century. It involves a rider attempting to stay atop a bucking bull for as long as possible. The event has become popular in other countries, and is now a major sport in many parts of the world. Bull-riding events are usually held in an arena, with the rider wearing protective gear and the bull being fitted with a flank strap to increase its bucking power. The rider is judged on their ability to stay on the bull for as long as possible, and the winner is the one who stays on the longest.
