He has completed 50 marathons in 50 days across 50 US states and on one occasion even ran non-stop for a staggering 80 hours over a distance of 350 miles without stopping to sleep.

Karnazes maintains that his superhuman endurance can be attributed to a rare condition that enables his body to rapidly flush lactic acid from his system faster than it can build up."At a certain level of intensity, I do feel like I can go a long way without tiring," he said. "No matter how hard I push, my muscles never seize up. That's kind of a nice thing if I plan to run a long way."

Despite doing well at sports in school, Karnazes didn't pursue running seriously until he was 30.

"I don't care how fast I go," he said. "I care about how far I go."
