Runners Show Less Fatigue After 200 Miles Than 100 Miles

New study shows role of pacing and sleep deprivation in endurance. 

Runners compete in the 89km Comrades Marathon between Pietermaritzburg and Durban, May 24, 2009.  

Runners compete in the 89-kilometer (55-mile) Comrades Marathon between Pietermaritzburg and Durban, South Africa, on May 24, 2009.

Running the Tor des Geants is not for the faint of heart. Widely regarded as one of the world's toughest endurance events, the 210-mile (336-kilometer) foot race climbs through some of the steepest and wildest terrain in the Italian Alps, taking runners up and over some 25 major mountain passes and involving a total of more than 80,000 feet (24,000 meters) of vertical elevation gain.

The rules are simple. This is not a stage race. Whoever gets to the finish line first is the winner, simple as that. From the moment the starter's gun goes off in the mountain village of Courmeyeur, in Italy's Aosta Valley, competitors have 150 hours to complete the course. How, when, where, even if they get any sleep during the race is completely up to them. The focus is solely on getting to the finish.
