John Cappis 50K Fat Ass

June 27th 2026
Silverton, CO
19 Hours | 50 KM

Expect about 19,000ft of elevation gain, and to go over 6 peaks that are about 13,000ft tall or higher plus one more that is over 12,500ft. The terrain will be a mix of dirt and 4WD jeep roads(20%), single track trail(14%) and plenty of off-trail miles(66%). Due to the steepness, the altitude and the rugged footing, expect to average less than two miles per hour at best, unless you're one of the best ultrarunners in the world and then maybe you'll average close to three miles per hour. Also the course will not be marked -- you will need to carefully follow the map and written directions to stay on course and (HIGHLY RECOMMENDED) use the GPX file with your GPS watch and or phone app.
