Racer Check in & Bib Pickup

Check-in will be on Friday August 4 in Aspen Mountain Upper Gondola Plaza located at 601 E Dean St. All racers must check in on Friday between 4 – 7pm to sign a waiver and pick-up a racer bib. We will also have a gift bag for each racer. If you cannot make it during this time please reach out to Brendan at to make arrangements for day of pickup.


All racers will be required to check in the morning of the race prior to the start. This includes those that picked up their bib the previous day.

Start Details

The start for both distance races will be in Snowmass Base Village at 8:00am.


The full course will finish in gondola plaza at the base of Aspen Mountain. The two-mountain course will finish at the base of Tiehack on Buttermilk. Power of Two participants should continue on the bike path to the base of Aspen Mountain for the post race festivities.


Parking is available in the Snowmass Base Village garage. There is a free bus from the finish line in Aspen to Snowmass on RFTA. Free parking is also available at the Intercept Lot (intersection of Highway 82 and Brush Creek Road) with free buses to both start and finish locations.

Racer Bags

Each racer will be allowed to deposit one bag at the start that will be shuttled to either finish line. In an effort to reduce waste we will not provide a bag, please bring your own. Make sure your name and bib number are clearly written on the outside of the bag.

The course will be marked with red/white striped tape and directional signage with the event logo.
