Ben Shephard, Rochelle Humes and Chris Kamara present the physical gameshow.
With brand new obstacles to face, the course is more extreme than ever, and in this episode former McFly star Harry Judd, GB Paralympian Dan Powell and a Rainbow Unicorn are among the competitors taking their turn and trying to defeat it.
Who will be triumphant, conquer the course and get the chance to climb the 22-metre rope climb to the top of Mount Midoriyama?
