The six fighting bulls that will take part in the evening bullfight start the run accompanied by an initial group of mansos, which act as "guides" to help the bulls cover the route. Two minutes after leaving the corral in Santo Domingo, a second group of bullocks (the so-called "sweep-up" group), which are slower and smaller than the first one, are let out to lead any bulls that might have stopped or been left behind in the bull run towards the bullring.
