Circus Odelay - 5k ThrillSeeker Experience Temecula, Temecula

The only thing crazier than running the 5k ThrillSeeker Stunt Run would be running the 5k ThrillSeeker Stunt Run backward. The 3.1-mile course includes such Hollywood-stunt-producer-designed obstacles as the Jugglernaught, where runners dodge giant foam bowling pins; the Punch Wall, which tries to knock participants off a 6-inch-wide ledge into a pool of water; and the Pole Vault, which launches racers over a stunt-pad canyon and down a 12-foot slide. Dressed as everything from Oompa-Loompas to marathon runners, runners don't just have a great time—they also help do good in the community through the organization's charitable donations.
