Race Rules

We hope for close-to-normal conditions on race day, as related to the COVID-19 pandemic. Current race information reflects a normal year.  Details may change as race day approaches, and any changes will be communicated to registered runners well in advance.  For reference, here are the 2020 COVID Safety Protocols.

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 100km race will be limited to 24 hours and will end at 5:30am on Sunday August 1st. We will adjust the cut off times accordingly if the race does not start exactly on time.

The 60km race will have an overall time limit, TBD. 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:

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 are expected to have the capacity to carry a minimum of 20 oz of water, whether in a bottle or a hydration pack. Dixie cups may be available at aid stations for carbonated beverages, but they cannot be carried out of the aid station.


  • 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 for the 100km, Pacers will be allowed starting at the Canadian aid station. Pacers may meet their runners at Canadian (48.0), or Bockman Road (52.7). Canadian is accessible on foot from the trailhead at the end of CR41. It is approximately 1 mile of gentle downhill dirt road to the Canadian aid station.
  • Pacers may not provide any assistance to their runners and are only allowed for safety and moral support.
  • Pacers will not be allowed for the 60km.


  • 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.

  • 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.
