Advance registration is required. There will be no race day registration. UPDATE This year we will have 2 divisions - 50 Mile Solo Racer, 50 Mile Team of 2. The 25 Mile Solo Racer division has been eliminated due to the county health ordinance participant cap. If you are only interested in doing 1 lap we recommend finding a friend to make a team.

Aid Stations*

The aid stations will minimal offerings to decrease contact between staff and racers. Water and electrolyte mix will be given out in disposable cups that can be poured into water bottles by racers. Other basics will include items such as bars and gels that are individually wrapped.

  • 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.
