The Grand Traverse Mountain Run

The Grand Traverse Mountain Run is an ultramarathon from Mt. Crested Butte to Aspen, Colorado, following the route of the Grand Traverse Backcountry Ski race. The point-to-point course is 40 miles long and crosses the Elk Mountains.

The event features over 6,000 feet of elevation gain. There are five aid stations along the course, and drop bags are available at the Taylor Pass aid station and the finish line. Hydration and nutrition on course are provided by official sponsors.

All participants are required to carry mandatory gear, including a waterproof windshield with hood, a hat or buff, and gloves. A Colorado Outdoor Search and Rescue (CORSAR) Card or a current Colorado hunting/fishing license is also required for entry.
