Dean Karnazes has a rare genetic condition that enables him to run continuously for days at a time.
The 53-year-old athlete is certainly no stranger to endurance running having competed in some of the world's toughest races including one which took him across the frozen wastes of Antarctica.
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."
