Barrel racing is a rodeo event in which a horse and rider attempt to complete a cloverleaf pattern around preset barrels in the fastest time. Though both boys and girls compete at the youth level, in collegiate and professional ranks, it is a rodeo event for women. It combines the horse's athletic ability and the horsemanship skills of a rider in order to safely and successfully maneuver a horse in a pattern around three barrels (typically three fifty-five gallon metal or plastic drums) placed in a triangle in the center of an arena.
