Season 4 Episode 2
As the competition kicks off at Venice Beach, athletes across the Southwest compete for a chance to take on the World's Most Difficult Obstacle Course. However, only 30 will move on to the Southwest regional finals. Will 53-year-old Kelvin Antoine, who calls himself the grandpa ninja, finish the course--or will Hollywood stuntman Levi Meeuwenberg, who's made it to Mt. Midoriyama a record five times? See their attempts, and feast your eyes on a 61-year-old pole dancer, Robert Pattinson's stunt double and a self taught parkour athlete do their best.
