38 Mile Course (60k)

Saturday, August 25, 2018 • 5:00am Start At Oak Street Plaza (Base of the Gondola)

The original and infamous TMR route- with one significant change. In the words of race founder, Dakota Jones- "The course is really hard". It is 38 miles with about 14,000 ft of climbing. You will go over 13,000 ft twice along with two additional climbs over 12,000 ft.

If the race wasn't challenging enough we have made one significant change to the old TMR route that includes 1.5 miles of sharp ridgeline above 13,000 ft between Ajax Peak and Imogene Pass. Not to mention the 13,500 ft summit of Telluride Peak along the ridge. We are calling this new section the "Mile and a Half of Sky".

You should know... there are sections of this course that are extremely technical, steep and loose. This is a MOUNTAIN RUN- participants will be running to altitudes of over 13,000 ft on exposed ridgelines and steep, rocky summits. The trails are extremely rocky and at times there are no trails at all. There are many sections of this course that will be exposed to falls, potential rockfall and hazardous weather. There will be safety personnel along sections of the route monitoring these hazards but all participants should be responsible for their own safety. THIS IS NOT AN EVENT FOR BEGINNERS.

*Cut-off times will be strictly enforced for the safety of the runners.

38 mile Drop Bags:

38 mile runners will be allowed to have two drop bags- Bridalveil Station and Mill Creek Station. All drop bags must be marked with your bib number and dropped off during packet pick up on Friday.


The 38 mile race starts at 5am and it will be dark. You will have the option to leave your headlamp at Gold Hill Station (#1) if you do not wish to carry it to your drop bag at Bridalveil Station (#2). If you choose to leave yours there please have it clearly marked with your bib number so that it can be returned to you at the finish line. headlamps can be claimed at the same place you will retrieve your drop bags.


We encourage spectators to cheer on the runners along the course. However, most of the aid stations that are accessible by vehicles have very limited parking. If you would like to visit the Bridalveil or Mill Creek aid stations please park at the bottom of the road and hike to the station. The hike to the Bridalveil Station is roughly a two miles and passes the iconic Bridalveil Falls. It is about a half mile hike up the Mill Creek Road to the Mill Creek aid station.

Course Markings:

The course will be well marked with flagging tape, flags and at some intersections, directional signs. The race organizers will do everything they can to have the course well marked for race participants the day of the event. Runners must follow trail markings and not cut switchbacks. Please be sure to understand the course! This is super important- Despite all our efforts to mark the course really well, some of our route marking have gone missing every year. We will be posting a more detailed route description and GPS track later this summer after the snow has melted.
