June 17 Update: We have received approval from all of the necessary local agencies. Kendall Mountain is ON! Please check your email for details. If you are interested in signing up, please join our waitlist and we will send you an invitation to complete your registration.

This year’s event will take place with approved modifications from the Town of Silverton, San Juan County & the Bureau of Land Management. We will have socially distanced wave starts of just 10 runners at a time every 5 minutes. Our normal start will now be spread out between 6:30am & 8:30am. We will do everything we can to make this event as contactless as possible from packet pickup to aid stations and the finish line. Runners & spectators will be required to wear masks unless running or eating.

Additionally, runners will be expected to be more self sufficient than normal and aid stations will feature only pre-packaged nutrition. One other change is the creation of a lollipop loop at the top of Kendall Mountain to eliminate the out and back section of single track. Instead, once summiting you’ll go “up and over” to the Town side of the mountain before picking back up the jeep road and heading back down the mountain.

We will publish additional information to make your trip to Silverton as safe as possible for you and the Town.

Course Summary The 43rd Annual Kendall Mountain Run features a jeep road climb starting from the mountain town of Silverton, Colorado at 9,318 feet to within 300 vertical feet of the summit. The course features a final scramble to the top of 13,066 Kendall Mountain and then returns back down to the finish in Memorial Park! There will be a shorter 11 kilometer option that will turn around at Deer Park.

This year, participants in the 12-miler will summit Kendall Mountain, then return by going over the backside of the mountain to link up with the original course at the “Notch”. This will allow for greater social distancing in the narrow scramble section. See the map below.


Aid Stations There will be two aid stations along the course that are each accessed twice. They will feature water, carbohydrate drinks, and pre-packaged snacks.

“An earlier rendering of the dash up the mountain during Silverton’s boom days — in August 1908 to be precise — predates the modern day version of the race. On Monday, August 24, 1908, miner Neil McQuieg raced to the top of 13,066-foot Kendall Mountain and back to town on a bet that he could do it in less than an hour and a half. He lost the bet, but only by a minute and 42 seconds.”

Trail Running & Trash
Please respect the trails and the beauty of the land by disposing of any trash at one of our aid stations. Do not throw trash on the ground–runners caught littering will be disqualified. We ask that you practice “Leave No Trace” along the course to ensure the race continues for many years.

Cupless Race
In our continued effort to reduce our races footprint and preserve the trails we love, the 2020 Kendall Mountain Run will be a cupless event.
What does that mean? There will be no paper cups at the aid stations at this race. Runners will be responsible for carrying their own container to refill along the way. UltrAspire reusable cups may be purchased with registration or on race day OR we encourage you to bring your own! Grab a cup, a hydration vest, pouch, or water bottle and we will fill it at each aid station along the way. We ask you to help us in our efforts by preparing for a cup free race day and thank you in advance for being good stewards of the trails!

Race Timing
All runners will be provided with a race bib that must be worn at all times during the race. You will be checked in and out of all aid stations on the course. There will be chip timing at the finish line and your result will show up on the display screen.

Aid Station Helpers
This event would not be possible without the help of our amazing volunteers! Sign Up Here!
