The bulls are better tempered, slower and their horns have been blunted, and this definitely isn't Pamplona.
But they're still bulls, and nearly two dozen of them will be chasing after hundreds of humans on a quarter-mile track in the small town of Cave Creek starting Friday.
The event is loosely fashioned after the annual running of the bulls in Spain.
Organizers say although Cave Creek's event is similar, it is safer because they're using rodeo bulls, not fighting bulls, and runners will have plenty of escape routes.
Still, the run carries enough risks that participants have to sign a lengthy liability waiver and medical form.
Organizers say they guarantee that runners "will have more of a rush than they've ever had in their lives."
