Erik Weihenmayer is the only blind person to climb the seven summits.  He also solo kayaked 277 miles of the Grand Canyon. He has done all of this and more, blind.  Weihenmayer, who lost his sight at 13, suffers from a genetic disease that eventually took his vision. He talks about what it takes to mentally and emotionally overcome his challenges and what motivates him to engage in adventuring that many sighted people would find near impossible.  Erik’s book about kayaking is called “No Barriers,” and is a must read.  Commander Divine and Erik get into what it takes to take the first steps to live a life of risk and adventure. Keep listening after the interview for a brief out-take regarding Erik’s upcoming trip to the Himalayas and Mark’s Spartan 300 march in Greece.
