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

Cut-Off Times & DNF

Friday: Fun Ride support ends at 5:30p. 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.

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

  • Ozark 50 riders arriving after 11:30a at the intersection of Back 40 & Flo Ride (19 miles into the course) will be re-routed and considered a DNF.
  • Ozark 30 riders arriving after 12:00p at the Pinyon Creek Aid Station (14 mi. mark) will be monitored by the Backcountry Director for further progress along the course.

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 OZ Trails 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.
