Event Description

Have you ever stood at the bottom of a mountain, staring up at the top, thinking to yourself: “I wonder if I could run all the way up there?” Well, now you’re going to find out!

The Mountain Marmot Trail Run is an epic trail race. The course is simple — start at the bottom of the mountain… run to the top. Sounds hard? Yeah, it’s going to take some work. But think how great you will feel when you make it to the top!

One thing is for sure… You won’t find a more beautiful course anywhere around. You’ll be running some of the most amazing single-track trails in Colorado, right as the Fall colors are just starting to change. The views will be stunning. This is a race you will never forget.

The distance is 12 miles. Because of the amount of climbing, think of it more as a half-marathon. The best part is, the second half of the race is entirely downhill! If you have run similar races like Imogene, Kendall Mountain, or Kennebec Challenge, you will find this race to be easier by comparison… but still plenty challenging.

And because it’s such an impressive accomplishment, we’ll have a post-race celebration worthy of your effort. Once you cross the finish line, there's great food, beer, live music, and festivities… all included in your entry fee!

Age Requirement:

Due to the nature of this event, participants between the age of 12 - 15 must sign up with a parent or other responsible adult, AND they must agree that they will run the entire race together.  Participants under the age of 12 are not allowed to participate.

Packet Pickup:

If possible, please come on Friday as this makes race morning easier for everyone.

  • Friday, September 21, 4 - 6pm, at Durango Running Company, 473 E. College Drive.
  • Race morning, 7:30 - 8:30am, Purgy's restaurant at Purgatory Resort.  Please arrive and check in by 8:30am to ensure that we can get the race started promptly at 9am.


There is plenty of free parking at Purgatory Resort.  From the main lot, you are 100 yards from the base area of the Resort.

Race Course:

The course starts at the base area of Purgatory Resort near Lift 1 and follows single-track trails up the mountain to the top of Lift 8, the highest point on the mountain.  The elevation gain is roughly 1800 feet.  The course will be well marked and easy to follow.  This is some of the most beautiful running terrain you will ever find!

Don't be intimidated!  While it sounds hard, this run is very doable.  The trails are non-technical, and the grade is fairly steady throughout, making it easy to get into a nice rhythm as you run.  Unlike other trail races that take you deep into the backcountry, in this race you will feel relatively close to civilization.  Even when you are five miles out, you will be passing by Resort warming huts and ski lifts, and you will always be able to orient yourself back to the base area of the mountain.

Aid Stations:

There will be four aid stations on the course, located roughly at mile 2.6, 4.5, 6.7 (summit) and 9.4.  The aid stations will provide water, snacks, first aid, and a cheering section.  Due to the nature of this race, you are also encouraged to carry your own water so you can hydrate when you need to.

Weather & Appropriate Clothing:

This is a high-altitude running event in late September, which means you must be prepared for all types of weather, including intense sun, warm temperatures, rain, cold temperatures, and possibly snow.  Typically, the weather in late September is beautiful for running.  However, you are responsible for checking the weather report and having the appropriate types of clothing and layers.

The race director, in conjunction with Purgatory Resort's risk manager, reserve the right to cancel or modify the race due to weather if there are concerns about participant safety.

Bag Check:

We will have an area at the start/finish line for you to leave a bag for after the race.


All participants will receive a fantastic finisher's medal worthy of this impressive accomplishment.  Top male and female in each age group will receive first place prizes.  Each runner will also receive a great race shirt included with your entry fee.

Post-Race Party:

Stick around after the race for a great party!  Every runner will get a fantastic breakfast burrito and a beer or soft drink, plus enjoy live music on Purgy's patio.  The awards ceremony will start at noon.
