I watched the documentary on Leo Houlding a few weeks back. He got some balls!! 3000ft climb.
Two men have free climbed the Dawn Wall of Yosemite's El Capitan rock formation, a feat no-one has ever managed before. The 3,000-foot (914m) sheer granite face is one of the most difficult climbs in the world and frighteningly smooth. How did they hold on?
"The holds are quite literally matchsticks on a vertical face," says Leo Houlding, a professional climber who has climbed El Capitan by a different route.
"Your main point of contact when you are climbing is the tips of your fingers and obviously hanging on to tiny little holds with all your bodyweight, and all the power you can create, starts to shred your fingertips," Houlding says.
"And after a week you have very little skin left."
Tommy Caldwell and Kevin Jorgeson, the two climbers who completed their epic climb on Wednesday, had been on the wall since 27 December - two-and-a-half weeks.
