250 ambitious competitors will start, but few will successfully overcome the tough obstacle course. Can any survive to the end to face the challenge of scaling the heights of the tower known as Mount Midoriyama and be crowned as a Ninja Warrior UK?

Competing are Dancing on Ice professional skater Sylvain Longchambon, singer Joe McElderry and Olympian snowboarder Aimee Fuller, but only those who complete the course and scale the four-metre Warped Wall will progress to the semi-finals.

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 and get the chance to climb to the top of Mount Midoriyama.

It's the second part of 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.

It's `The Eliminator'. Only the toughest competitors who complete the course against the clock will survive and go through to the Grand Final and get the chance to attempt the 22-metre rope climb to the top of Mount Midoriyama.

It's the Grand Final, and with only 15 contestants remaining facing the very toughest obstacles that the course has to offer. One of them could be the one to finally make it to the top of Mount Midoriyama to become the first ever Ninja Warrior UK.
