Those mad adrenaline- (and sometimes alcohol-) infused half-mile dashes dodging 1,800-pound stampeding bulls have begun through the streets of Pamplona, Spain. Part-spectacle, part-tradition, the Running of the Bulls is the most celebrated slice of the nine-day San Fermin Festival. In addition to the daily runs, events include bullfighting and a parade featuring a statue of Pamplona's first bishop, St. Fermin. Pleads for safety and prayers of thanksgiving to St. Fermin traditionally begin and end the run through the streets, which was famously depicted in Ernest Hemingway's "The Sun Also Rises." Concluding on the 14th of July every year, attendees gather on the town hall plaza at midnight for singing by candlelight.
