In 2001, Erik Weihenmayer became the only blind person to reach the summit of Mt. Everest. And in 2008 he climbed Carstensz Pyramid on the island of Papua New Guinea, completing the Seven Summits, the highest point on every continent.
It was 13-year journey, beginning with his ascent of Denali in 1995. Only 150 mountaineers have accomplished the feat.
Since then, he has authored multiple books, including a memoir, Touch the Top of the World.
Weihenmayer has co-founded a movement called No Barriers, whose motto is "What's within you is stronger than what's in your way."
In 2014 he kayaked the entire 277-miles of the Colorado River through the Grand Canyon.
