Large snowpack, avalanche debris force cancellation of Hardrock 100 endurance run
SILVERTON, Colo. -- This year's Hardrock 100 endurance race, one of the most difficult ultraruns in the world that attracts athletes from around the world, was canceled Monday because of high snowpack and avalanche debris, organizers said. The race, which includes a lottery for would-be competitors, features runners who must climb and descend 33,000 feet over 100.5 miles in less than 48 hours in the San Juan Mountains in southwest Colorado.
