In May 2002, Weihenmayer, a strapping mountaineer, runner, cyclist and acrobatic skydiver from Denver, Colorado, reached the top of Everest. Weihenmayer likely would have joined a long list of uncelebrated summiters were it not for the fact that he is completely blind. Rather than fading into obscurity, his feat was trumpeted around the world, garnering him a cover photo on Time magazine, and landing him spots on the Today Show and NBC Nightly News with Tom Brokaw. The climber has gone on to become one of the country’s most sought-after motivational speakers. He hasn’t exactly retired from adventure, either. In 2010, he finished the Leadville 100 mountain bike race. Last year, Weheinmayer returned to the Himalayas with a team of wounded veterans, helping lead them to the top of Lobuche, a 20,075-foot peak a few miles from Everest.
