A rodeo contestant is someone who participates in a rodeo, which is a competitive event that features traditional rodeo events such as bull riding, calf roping, and barrel racing. The two main roles of a rodeo contestant are a roper and a RIDER. A roper is someone who uses a lasso to catch a calf or steer, while a RIDER is someone who rides a horse or bull. Both roles require skill and courage, and the contestants compete for prizes and recognition.
