Kennebec Mountain Run

Date: 7/25/2020
Time: 8:00 am - 1:00 pm
Location: La Plata Canyon

The Kennebec Mountain Run is a tough, scenic 15ish-mile trail run through the La Plata Mountains, just west of Durango in southwest Colorado. Some people like to say that KMR is a perfect tune-up for the Imogene Pass Run, but really, Imogene is a perfect cool-down after Kennebec, and a wonderful introduction to the La Platas!

Proceeds benefit La Plata County Search & Rescue.

Directions, Carpool & Parking

  • Driving from Durango (about 30 minutes):

    • Drive 11 miles west of Durango on US-160.

    • Turn north onto La Plata Canyon Road (CR 124) at the Kennebec Cafe.

    • Proceed 5 miles to Mayday (just beyond end of pavement).

  • IMPORTANT: Only vehicles carrying 3 or more persons may proceed the remaining 3 miles to La Plata Campground. ALL others must park at Mayday and jump in with another driver to create a carpool. (Your best bet is to carpool from Durango!) You can also take your bike and ride from Mayday to La Plata Campground (or be a real stud and bike all the way from town!).

  • Vehicles parking at La Plata Campground must turn around at the start/finish area and park on the southbound shoulder.

  • Do not obstruct traffic on CR 124 or access to La Plata Campground.

  • Please respect our parking marshals and help us stay in good favor with the USFS. You can contact the RD with any questions.

Start Times

  • The race begins at 8:00 a.m.

  • A quick briefing will take place 5 minutes prior to start.

  • Early start begins at 7:00 a.m. If you expect to need 5 or more hours to finish, you may opt to start early. Please just show up early on race morning, then we’ll write down all the names of the early starters at the starting line. Note: please do not take the early start just so you can “finish early”, as this is intended for people who truly need more time to finish. If you do take the early start, you will be ineligible for placing awards and your fastest official finishing time will be 4 hours.

  • There will be a STRICT cut-off time of 10:30 a.m. at the 6.3 mile point, either Kennebec Pass (clockwise) or Cumberland Basin (counterclockwise). If you don’t think you can make the cut-off, please opt for the early start.

Awards & Post-Race

  • 1st place overall male and female each win a highly-coveted fresh-baked pie, among other goodies!

  • We will also raffle off random prizes from our sponsors.

  • Local food and drinks, awards ceremony (around noon), and an opportunity to soak in the river!


  • Events like the Kennebec Mountain Run are impossible without volunteers. Thank you for generously donating your time!

  • If you, a friend or a family member are interested in volunteering before, during, or after the race, please contact the RD.
