The Running of the Bulls (in Basque, entzierro; in Spanish, el encierro - both literally, "the enclosing") is a practice that involves running in front of bulls that have been let loose on a course of a sectione-off subset of a town's streets; roughly 754 metres (825 yards). The most famous running of the bulls is that of the nine-day festival of San Fermín in Pamplona, although they are held in towns and villages across Spain during the fiesta season, usually in the run-up to the corrida, or bullfight, and in some cities in southern France, most notably Bayonne. Unlike bullfights, which are performed by professionals, anyone may participate in an encierro. Injuries are common, both to the participants who may be gored or trampled, and to the bulls, whose hooves grip poorly on the paved or cobbled street surfaces.
