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.
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.
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
There are 4 cut-off points on the course:
