36-year-old Tommy Caldwell and 30-year-old Kevin Jorgeson have taken on an incredible challenge. Using only their feet and hands, they are climbing El Capitan, a 3,000 foot granite monolith in Yosemite National Park. Known as one of the world's most challenging cliff climbing routes, the sheer face in California is no easy feat to ascend.
Although the pair are using ropes in their climb, they are not used as aids, but as protection against potential falls. Add this to the fact that the pair need tape and glue to fix cuts to their fingers from the often razor sharp rocks, and you will see just how unbelievably difficult the task is. In fact, the men have often to spend whole rest days in their tents perched on the rock face in order to heal. Preferring to climb at dusk rather than in the daytime sun so their hands don't sweat as much, the team use solar powered devices and have their provisions air dropped in order to travel as light as possible.
