The John Cappis

The John Cappis is a challenging endurance peakbagging event held near Silverton, Colorado, featuring a roughly 50k course with about 19,000 feet of elevation gain. Participants summit multiple peaks in the rugged San Juan Mountains, navigating an unmarked, mostly off-trail route with elevations ranging from 9,300 to over 13,300 feet. The event honors John Cappis, a Hardrock 100 founder and mountain running pioneer.

It demands advanced mountain experience, including off-trail navigation and hazard assessment, with limited support and a 19-hour cutoff. The course varies yearly, emphasizing self-sufficiency and technical skill in a remote, high-altitude environment. Visit the organization's website for the most recent information.
