The origin of this event comes from the need to transport the bulls from the fields outside the city, where they were bred, to the bullring, where they would be killed in the evening. During this ' run ', 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.
