At 14-years-old, Erik Weihenmayer lost his eyesight to a rare disease. He was devastated, feeling the crushing grip of loneliness and perceiving a limited future. Then, a rock climbing trip to North Conway, NH changed his perspective on what was possible. Erik has used his blindness, his so-called barrier, to charge to the top of Everest, propel himself through the rapids of the Grand Canyon, and as fuel to pass on his passion for adventuring to others.
