America's Uphill Challenging all racers for a grueling hill-climb

Attention Racers-

Just a few moments ago, the Aspen Mountain Ski Patrol deemed the conditions too dangerous to hold America’s Uphill. There is 13″ at the Mid Station on Ajax and due to avalanche danger and control, we have to cancel the race. While we are disappointed, your safety is our first concern.

Give us a few days to get organized and look for an email regarding refund details.

We hope to see you back next year.

The Race Organizers,

Ute Mountaineer and City of Aspen Special Events Department.

The America’s Uphill is a longtime Aspen favorite that attracts hundreds of racers each year. The race brings together snowshoers, runners, Nordic skiers, telemark skiers, and Randonee skiers for a 2.5 mile and 3,000’+ vertical climb up Aspen Mountain.

Course DescriptionAmUphillApplication-New09.pub

The America’s Uphill begins at the base of Little Nell and climbs 3267 feet up the Aspen Mountain ski area finishing at the Sundeck Restaurant at an elevation of 11,212 feet. The course follows Little Nell to the Bell Mountain Chair and then up Bingo Slot to Spar Gulch. The long steep climb up Spar continues to the base of Ajax Express (Lift 3). From there, there’s a small reprieve on Tortilla Flats before the climb begins again in earnest. At this point, the race follows a maze of trails starting up Deer Park to Pussyfoot, Silverbell, and Easy Chair, finally topping out at the Sundeck. Inspection of the course prior to race day is recommended.

There is one aid station with fluids at the base of Lift 3.
