Participants must be over 18, physically fit and not be under the influence of alcohol to participate in the run.
Each run features 6 bulls and 6 steers that run alongside. Three additional steers are set out of the corral 2 minutes after the initial set have been released.
The length of the run is only about 826 meters, meaning it is all over in about 12-15 seconds. But what a heart pumping 15 seconds they are!
