Grand Traverse Mountain Run
The Grand Traverse Mountain Run is a point-to-point ultramarathon held on September 5, 2026, running from Crested Butte to Aspen, Colorado. The course follows the route used by the Grand Traverse backcountry ski race and covers approximately 40 miles across the Elk Mountains with more than 6,000 feet of elevation gain. The event is operated as a fundraising race for Crested Butte Nordic, a 501(c)(3) recreational non-profit.
The course includes five aid stations and drop bag service at Taylor Pass (mile 23.5) and at the finish. The official hydration sponsor is Gnarly; Gnarly Hydrate and Fuel20 are provided on course. Aid stations offer a mix of full aid and limited aid items, including water, electrolytes, Honey Stinger products, snacks, fresh fruit, and select hot items at Taylor Pass.
Runners must carry mandatory gear: a waterproof windshield with hood, a hat or buff, and gloves. A Colorado Outdoor Search and Rescue card or a current Colorado hunting or fishing license is required and must be shown at bib pick-up. Tracking through MAProgress is mandatory for safety. Course markings are used, but portions may be run in low light and can be hard to see, so participants should be familiar with the route. Race policies state there are no refunds or entry transfers, a traditional waitlist is used, and cut-off times are strictly enforced.
Prize money is awarded to top male and female finishers and additional product awards are distributed to podium, age group, and randomly selected finishers. Visit the organization's website for the most recent information.
