Aid Stations & Rider Support Crews

Our wonderful volunteers will staff 3 Aid Stations throughout the weekend:

  1. Aspen Creek Aid Station (Friday Only)
  2. Copper Basin Aid Station (Sat & Sun)
  3. Skull Valley Aid Station (Sat & Sun)



Participants may receive “hand-ups” from their support crews at the following locations:

  • Aspen Creek Aid Station: access via Copper Basin Rd. Park beyond/past the Aid Station so that you’re not obstructing the participants.
  • Intersection of FR 373/Thumb Butte Rd and Copper Basin Rd (one mile from the top of the Skull Valley overlook).
  • Copper Basin Aid Station: only accessible by driving to the FR 373/Copper Basin intersection. Find a spot to park, then either walk or pedal to the aid station location. It’s roughly 2 miles downhill. For the safety of the participants, no vehicles are allowed on the course past FR 373/Copper Basin & Thumb Butte Circle intersection. Please pre-plan and do not drive to the aid station.
  • Skull Valley Aid Station: access via Iron Springs Rd.

Aid Station Fare

Each station will be equipped with V8 +Energy, cookies, oranges, pickles and Honey Stinger waffles.

If a rider prefers a different hydration mix or energy drink, we encourage them to bring their own and mix with the water provided on route.

Plan to start the event with a full hydration pack and plenty of food.

Cutoff Times & DNFs

Participants will be provided ample time to complete their distance. However, once the courses have been finalized, appropriate cutoff times and locations will be established to ensure that riders return to the finish before Course Support (Medical, Traffic, Police, Communications, Volunteers) ends.

If the Race Director anticipates that you won’t complete the course before the following time limits, you may be asked to reroute to the Start/Finish area along a pre-determined (and more direct) path.

  • Friday (15 Proof Fun Ride): Course support ends at 6:00p
  • Saturday (30 & 50 Proof Amateur Rides): Course support ends at 4:00p
  • Sunday (Professional Backcountry Race): Racers are expected to finish by 1:00p

All DNF (Did Not Finish) riders are expected to email, or report to the Timing Booth, to inform us that they are no longer on the course.

Riders cut off by the race director will be considered a DNF, along with DNFs due to medical issues and mechanical failures. DNF riders may receive 50% off registration for the following year’s Whiskey Off-Road, as a start line redemption opportunity.
