On January 14, 2015, rock climber Tommy Caldwell, along with his partner Kevin Jorgeson, summited what is widely regarded as the hardest climb in history - Yosemite’s nearly vertical 3,000-foot Dawn Wall.
After an arduous nineteen-day ascent, Caldwell and Jorgeson were the first to summit it without the assistance of ropes, other than to catch their falls. Caldwell’s odds-defying feat was the culmination of an entire lifetime of pushing himself to his limits as an athlete. In his new memoir The Push, he shares his story.
