number of bulls in running of the bulls
Running of the Bulls The Running of the Bulls (in Spanish: encierro, from the verb encerrar, "to corral, to enclose") is a practice that involves running in front of a small group of cattle, typically six, of the toro bravo breed that have been let loose on a course of a sectioned-off subset of a town's streets.[1]
Bull riding The bull bucks, rears, kicks, spins, and twists in an effort to throw the rider off. This continues for a number of seconds until the rider bucks off or dismounts after completing the ride. A loud buzzer or whistle announces the completion of an eight-second ride.
