With brand new obstacles to face, the course is more extreme than ever. In the third episode, more contestants try their luck against the toughest obstacle course on TV. Competing alongside them are Radio 1's Rickie Williams and Melvin Odoom and Love Island's Laura Crane, but only those who complete the course and scale the four-metre Warped Wall will progress to the next stage of the competition.

It's the semi-final, and with brand new obstacles to face, the course is more extreme than ever, as the best competitors from four heats return to fight it out for a place in the final.
