The John Cappis

The John Cappis is a challenging 50K mountaineering event held near Silverton, Colorado, featuring approximately 19,000 feet of elevation gain across rugged terrain. Participants summit several peaks around Silverton on an unmarked, mostly off-trail course with elevations ranging from 9,300 to 13,300 feet. The event honors John Cappis, a Hardrock 100 founder and mountain running pioneer.

With a 19-hour cutoff, the course demands advanced mountain experience, navigation skills, and preparedness for harsh conditions, including potential snow and stream crossings. Support is minimal, and the remote, technical nature makes this a demanding endurance challenge suited only for highly qualified mountain runners.
