Behind the Scenes of Kilian’s Inhuman Win at the Hardrock 100

Last weekend was the 26th running of the Hardrock 100, a brutal ultramarathon in Southwestern Colorado’s San Juan mountains that has an average elevation of 11,000 feet. The two-day event was filled with drama and excitement—defending co-champion Jason Schalrb was forced to drop at mile nine due to a stomach bug, and women’s race leader Caroline Chaverot took a wrong turn at mile 70. Most notably, though, Kilian Jornet won for the fourth year in a row, despite falling and dislocating his shoulder at mile 14, popping it back into place himself, and running the remaining 86 miles with his left arm in a makeshift sling. This victory came just two months after the 29-year-old Spaniard summited Everest twice in one week.
