Hiker who cut off arm does 100-mile race

LEADVILLE, Colo. - A little over a year after cutting off his arm to save his life during a solo hike in Utah, Aspen adventurer Aron Ralston has completed a grueling 100-mile race at over 10,000 feet elevation.

More than 400 runners began the Leadville Trail race before dawn on Saturday, racing through hail and lightning at times, but fewer than half officially completed the race. Some dropped out because of nausea and cramps and others weren't able to cross the finish line within the 30-hour time limit.

Ralston, an official finisher with a time of 29:43, said he got sick after eating an onion sandwich but continued running despite feeling nauseated.
