Watch these five minutes and know in your bones that Ueli Steck is one of the best mountaineers on earth. He picks and pulls up Eiger like the unstoppable second hand on an atomic Swiss clock. Tireless training and impeccable technique has paid off. In 2007, Steck sped up Eiger’s North Face in 3 hours, 54 minutes, smashing the previous speed record by more than 45 minutes. A year later he beat his own record by a full hour. Now Steck is taking on the Himalayas. They better watch out.
