Race Rules

Race rules are designed to provide a safe and fair experience for everyone involved and to help ensure our ability to produce the race again next year.

Major rule infractions by racers will result in immediate disqualification. Please do not argue with or harass our volunteers but feel free to direct any questions or complaints to Nick or Brad at racedirector@gnarrunners.com.

Course Cut Offs

The race will be limited to 24 hours and will end at 5:30am on Sunday July 26th. We will adjust the cut off times accordingly if the race does not start exactly on time.

Course cut offs will be enforced at the following aid stations:

  • Diamond (Mile 17.2) at 11:45am. 6:15 Total time.
  • Ruby Jewel (Mile 29.4) at 4:20pm. 10:50 Total time.
  • Clear Lake (2nd stop Mile 43.9) at 10:45pm. 17:15 Total time.
  • Canadian Yurt (Mile 50.1) at 1:00am. 19:30 Total time.
  • Bockman (Mile 55.8) at 3:00am. 21:30 Total time.

Note: Course cut offs should not be used for pacing targets to reach the finish within 24 hours. These cut offs have been set to give runners the maximum time on course and to ensure that volunteers can shut down and clean up within a reasonable time frame.

Bib Numbers and Check in

  • All Runners are required to check in prior to the race start. Runners who do not check in will not be officially entered into the race and will not be recognized in the final results.
  • At each aid station volunteers will record runner bib numbers. Runners are responsible for making sure that aid station volunteers record their number. Please make sure that your bib number is visible from the front and call out and confirm your number when passing through an aid station. This is important so that we can keep track of runners and know that you are not lost or injured.

Dropping Out

  • If you need to drop out of the race for any reason, you must check out with the nearest aid station captain and turn in your race bib. If you do not inform us that you have dropped, we will assume that you are lost on the course. You will be held responsible for any Search and Rescue fees incurred.


  • There will be no water cups at the aid stations. Bottles can be filled at aid stations. Bottles or other supplies may not be stashed along the course. All runners must have the capacity to carry a minimum of 20 oz of water, whether in a bottle or a hydration pack. Dixie cups will be available at aid stations for carbonated beverages, but they cannot be carried out of the aid station.

No Headphones or iPods

  • Per the terms of our insurance coverage, we need to ask runners not to run with headphones. This will be a pain in the rear end for some, we are sure, but the sounds of nature are part of the experience too.


  • Purposeful littering is prohibited and will result in an immediate disqualification. Carry garbage to aid stations and dispose of trash in proper garbage containers or hand garbage to a volunteer. We recommend that you carry an extra baggie to stash small wrappers and gel tabs that can easily be dropped by accident.

Stay on the Course

  • No short cutting. Please follow course markings as closely as possible.

Yield to Pedestrians and Horses

  • The trail system will be open to the public during the race. Pedestrians and Horses always have the right of way. Please be courteous and respect other people on the trail system. When approaching horses, talk to the rider and always wait until they give you permission to pass. Most riders will move their horses off the trail for you. Always try to assume higher ground when crossing paths with horses.
  • Mountain bikers are required to yield to runners but for your own safety, please use common sense and watch for blind corners and be careful when passing bikers.


  • For added safety at night, Pacers will be allowed starting at the Canadian aid station. Pacers may meet their runners at Canadian (50.1), or Bockman Road (55.8). Canadian is accessible on foot from the trailhead at the end of CR41. It is approximately 1 mile to the Canadian aid station.
  • For runners over the age of 60, we are allowing pacers beginning at the Ruby Jewel aid station (29.4). Pacers will need to park on the Ruby Jewel Rd below the Francisco Loop Rd and walk/run up to the Ruby Jewel aid station (1-2 miles).
  • The last 2 miles from the Ranger Lakes Road Crossing to the finish will be open for any family and friends to join their runner. Parking at Ranger Lakes is limited so please plan on running the 2 miles back from the finish to meet your runner. Pacers may not provide any assistance to their runners and are only allowed for safety and moral support.


  • Runners may not receive any additional crew aid outside of designated aid stations. Crewing on the course will result in the immediate disqualification of the runner.
  • Click here for detailed directions to crew access points.
  • No Parking Anywhere on Highway 14.
  • No Crew Vehicle Access on the Montgomery Pass jeep road.
  • No Crew Vehicle Access on the Ruby Jewel Road past the Francisco junction.

Drop Bags

  • Click here for a detailed list of drop bag locations.
  • Drop bags may be dropped off at the Gould Community Center at the pre-race check-in between 3-7pm on Friday 7/24.
  • Runners may also leave a drop or finish line bag at the Gould Community Center start/finish area on race morning before the start.
  • Please limit your drop bags to the size of a small duffel bag, day pack, or stuff sack (approximately 16in x 12in x 8in or smaller). Volunteers have limited space to transport drop bags so please do not over-pack. You will only be out on the course for a maximum 24 hours.
  • We will not be responsible for any lost or stolen items so please do not leave any valuables in your drop bags.


  • Dogs are not allowed on the course with runners. Well behaved dogs are welcome at the Gould Community Center, aid stations, and park trailheads. Dogs must be on a 6ft leash at all times – no flexi leads or long lines and do not leave your dog tied or unattended. Please keep your dogs out of the aid station tents and out of the runner traffic lanes.


  • Please do not leave any valuables at the start/finish or aid stations. Volunteers are not responsible for returning items left behind at aid stations. We are not responsible for any lost or stolen items.
