Barrel racing involves three barrels set in a triangular pattern that horses must run around quickly. Barrel horses have distinctive physical traits like a round hip and steep shoulder to help them maneuver quickly, and can cost between $1,000 to over $50,000. Barrel racing competitions are popular across the U.S., with one of the largest events being the National Barrel Horse Finals in Las Vegas, Nevada. Many rodeo events originated from the real tasks of cattle ranching in the American West.
