The first of two semi-finals will see the first 32 competitors, including new and fan favourite ninjas, taking on the Snake Run, Rolling Log, Diving Boards, Ring Toss, Sling Shot, Warped Wall, Barrel Roll, Spider Jump and Invisible Ladder in one of the hardest semi-final courses ever. The 12 competitors who make it the furthest the fastest will advance to the Grand Final. The Ninja versus Ninja battle steps up a gear when a new set of obstacles on the Power Tower await the two furthest fastest competitors as they battle it out for a second chance advantage in the Grand Final.
