Cutoff Times & DNFs

Friday: Fun Ride support ends at 6:00 pm. If the race director anticipates you may not make this time limit, you may be asked to reroute in the most direct manner to the finish.

Saturday: In order to ensure riders return to the finish before course support (Medical, Traffic, Police, Comm, Volunteers) ends at 4:00 pm, the following cutoff has been established:

  • 12:30 PM at White Rock Trailhead Parking Lot (16 mile point for the 30 Proof, and 31 mile point for the 50 Proof)

Sunday: Racers are expected to finish by 1:30p. If the race director anticipates you may not make this time limit, you may be asked to reroute in the most direct manner to the finish.

Riders cut off by the race director will be considered a DNF (Did Not Finish), along with DNFs due to medical issues and mechanical failures. DNF riders may receive 50% Off on the following year’s Whiskey Off-Road registration as a start line redemption opportunity.

All DNF riders are expected to report to the Epic Rides tent to notify an Epic Rides crew member that they are no longer on the course.
