The Running of the Bulls is a part of the famous San Fermin festival - a practice that involves running in front of a small group of bulls (typically a dozen) that have been let loose on a course of a sectioned-off subset of a town's streets. A first rocket is set off at 8 a.m. to alert the runners that the corral gate is open. A second rocket signals that all six bulls have been released. The third and fourth rockets are signals that all of the herd has entered the bullring and its corral respectively, marking the end of the event. Every year between 200 and 300 people are injured during the run although most injuries are contusions due to falls and are not serious. So you think you're up for it?
