American Ninja Warrior travels to Denver, Colorado where competitors tackle not only the elevation, but four new obstacles including the Rolling Log, Rotating Bridge, Jump Hang Kai and Grip Hang. Professional snowboarder Graham Watanabe competes, as well as rock-climbing veteran Nikole Muckelroy and her fiancé Conner Moyer.
G4 presents the biggest and most daring Ninja Warrior event in the network's history with the new series American Ninja Warrior.
The series will hold open tryouts to find the top 10 American competitors from across the country and send them to Japan to tackle Sasuke, the world's most difficult and diabolical obstacle course.
The American competitor who completes all four stages of Sasuke in the fastest time will be named the ultimate American Ninja Warrior.
