This past week, more than 7,500 trail runners from 77 countries converged on Chamonix, France, for five races connected to the Ultra-Trail du Mont-Blanc. Included in that mix were more than 180 American runners—an all-time high for the event that has grown dramatically since its inception in 2003. Rory Bosio, a pediatric intensive care nurse from Truckee, Calif., was the women’s winner in the 104-mile UTMB, while Jason Schlarb from Boulder, Colo., was fourth in the men’s UTMB race.
