The Hardrock 100 is one of the toughest 100 milers in the country. The course features 33,050 feet of vertical gain, at an average elevation of over 11,000 feet, through the rugged San Juan mountains of western Colorado.

The 2017 event saw no shortage of drama: race leader Kilian Jornet fell and dislocated his shoulder early on, while women’s leader Caroline Chaverot got off-course near mile 70 (she still won, despite losing nearly an hour trying to get back on course). Racers also had to contend with rain and hail up high.

This video, by Billy Yang, captures scenes of the race leaders as they battle through fatigue, cold and injury.
