Rocky Mountain Races is proud to present our newest race, The Aspen Loop Ultra.  This race is designed as a weekend event for the ultimate endurance athlete, ready to put themselves to the test.  Individuals can choose to race our 40 mile course as a run, a mountain bike, or show their true grit and complete both races in our dual race option.

All events start and finish at the Transfer Campground in Mancos, Colorado. The Aspen Loop is a 40 mile alpine loop located in the western San Juan National Forest. The loop starts from Transfer Campground along the north end of the West Mancos Canyon and consists of mostly narrow double track trails along with a mixture of single track and forest service roads. There are some steep climbs and a few rocky areas, but in general this is a very runnable / bikeable course. The highpoint of the course is reached in the first 9.5 miles, so the bulk of the climbing will come early on. The highpoint is followed by several (15ish) miles of gradual descent before racers start to regain some elevation toward the second peak at mile 34.
