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.

Both distances will finish at the same location on Fanny Hill just above the concert stage near the Snowmass Mall.

Cut-off time*

Racers competing in the 50 Mile events will need to begin their second lap by noon otherwise you will not be allowed to continue for safety reasons.


Parking is available in the Snowmass Base Village garage. Free parking is also available at the Brush Creek Lot (intersection of Highway 82 and Brush Creek Road) with free buses to Snowmass.

Racer Bags*

Each racer will be allowed to deposit one bag at the start/finish. 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.

Course Marking

The course will be marked with black & yellow striped tape and pink directional signage with the event logo.

Aid Stations*

The aid stations will have water, electrolyte mix, Red Bull, Coca Cola, pretzels, potato chips, candy and other snacks to keep you fueled.
You should plan to be able to make it from aid station to station without additional support.


  • Stay on the designated trails; no short-cutting switchbacks. Those attempting to take short-cuts will be disqualified and publicly shamed.
  • Headphones are permitted, but please be respectful when entering aid stations and crossing other trails. Be aware that the trails are open to the public and, in spots, cross other trails that may include cyclist, runners, hikers, etc. Please rock-out responsibly.
  • If you choose to drop out please alert the nearest aid station personnel. We do not want to worry your emergency contact person!
  • No littering! We have trash cans and recycle bins at each aid station. Just because it's a race doesn't mean you get to forget your manners.
  • If you must relieve yourself, please use a bathroom (available at Start/Finish, Town Park & Elk Camp restaurant) or discretion...
  • All riders must carry a water bottle or hydration pack.

Normal Mountain Operations*

We ask each racer to keep in mind that Snowmass will be open to guests as usual starting at 10am so please be respectful of the general public on the trails and aware of other users.

Racer Safety*

For the safety of every racer, each athlete is required to notify the closest course marshal of any injury or racer who appears to have ventured off-course ASAP. We will have plenty of medical staff available to assist along the course.

Racer Family Lift Tickets*

We will be offering 50% off vouchers for family members of racers who wish to watch/cheer from the top of Elk Camp Gondola in Snowmass. Vouchers will be available at registration.
