The most famous running of the bulls is that of the eight-day festival of Sanfermines in honour of Saint Fermin in Pamplona,[2] although they are also traditionally held in other places such as towns and villages across Spain, Portugal, in some cities in Mexico,[3] and southern France during the summer.
The origin of this event comes from the need to transport the bulls from the off-site corrals where they had spent the night, to the bullring where they would be killed in the evening. Youngsters would jump among them to show off their bravado. In Pamplona and other places, the six bulls in the event are still those that will feature in the afternoon bullfight of the same day.
