Course

At Midnight, racers set out from Crested Butte for Aspen, climbing through the Crested Butte Mountain Resort before racing to Taylor Pass and finishing with an exciting run down Aspen Mountain. Racers climb more than 7,800’ and travel more than 40 miles to complete the course. Finishers cross the finish line at the base of Aspen Mountain where they are welcomed by family, friends, live music and a sponsor expo.

Due to weather and snow safety considerations, the exact course cannot be finalized until race day. Race organizers may change the course based on snow conditions, weather or other safety concerns.  In extreme circumstances, the course may be modified to finish in Crested Butte rather than in Aspen.   The final course will be determined and described to racers at the Mandatory Race Meeting.

Route-Finding
The course is generally unmarked. Racers must find their own route to mandatory checkpoints. This is a backcountry race and participants will have extremely limited support once they are on the course.

Evacuations

Motorized vehicles are not allowed from Brush Creek to Star Pass, so a medical evacuation is by sled only. Racers must be prepared to self-rescue and be self-supported in the event of an emergency

Cut-Offs
There are 4 cut-off points on the course:

  • Refuge Checkpoint #1 – Teams must reach the Checkpoint by 7:00 AM. Teams that do not meet this cut-off will be turned around and must return to Crested Butte.

 

  • Star Pass Checkpoint – Teams must reach Star Pass by 8:00 AM. Teams that do not meet this cut-off will be turned around and must return to Crested Butte.

 

  • Refuge Checkpoint #2 – There is a mandatory 10-minute stop and medical check at the Checkpoint. Racers must reach the Checkpoint by 2:00 PM. Racers that do not meet this cut-off must ski to a pre-determined pick up point, where they will be escorted to the Sundeck and downloaded on the Aspen Gondola.

 

  • Aspen Mountain Gate Checkpoint – Teams must reach the top of Aspen Mountain by 4:00 PM. Racers that do not make this cut-off will be escorted to the Sundeck and downloaded on the Aspen Gondola.

IMPORTANT:  All information is subject to change.  For the safety of racers and volunteers, weather and snow conditions may require a change in the race start time or location, the official course, or race rules – or may lead to cancellation.  The registration fee is non-refundable. 

The Grand Traverse operates under a Special Use Permit on the Gunnison National Forest.
