9. The Zombie Run

For believers of the zombie apocalypse or just people who like the thrill of a good scare, the Zombie Run should be the run of choice, pitting humans against real-life zombies in a 3.1-mile obstacle course. Runners can elect to register as humans or receive a zombie makeover and run as otherworldly creatures. Humans receive a belt with three “life flags,” and must emerge from the obstacle course with at least one life flag remaining. The task isn’t as easy as it seems, with zombies chasing them the entire way. This year’s zombie apocalypse hits New York on October 25 at the Aviator Center in Brooklyn.
