Course Summary

The Kendall Mountain Run, presented by adidas Terrex, kicks off in downtown Silverton, Colorado, and takes runners on a jeep road ascent to a final 250-foot vertical scramble at the summit of Kendall Mountain. Towering at 13,066 feet, the summit offers breathtaking views of the town and the majestic San Juan Mountains. Starting at 9,318 feet, participants will tackle the climb, tag the summit, and descend down the backside of Kendall Mountain, linking back to the jeep road before finishing in historic Memorial Park in downtown Silverton.

Select the Mountain Duo registration option on the Silverton Alpine registration page to tackle both races and receive a discount!

Cupless Race

In our ongoing efforts to reduce our environmental footprint and preserve the trails, the Kendall Mountain Run will be a cupless event. There will be no paper cups at aid stations, and runners are responsible for carrying their own container. You can purchase an UltrAspire reusable cup during registration or on race day, or simply bring your own! Whether it’s a cup, hydration vest, pouch, or water bottle, we’ll fill it for you at each aid station. Thank you for helping us protect the trails and making race day cup-free!
