Additional Information

This event is not a COOL League scoring event and is open to the general public.

You will have two hours to visit as many control sites as possible to generate the highest score. Each control site has a question associated that you must answer to show that you visited that site. 

To protect the safety of our volunteers and participants, the following protocols will be in place at this event:

  • Attendance by Pre-registration only. No day of event registration.

  • Distributed posters with detailed race information instead of a large gathering for announcements.

  • Maintain social distancing while waiting for the mass start

  • Bring your own water and snacks. No water will be placed on the course. We will have single serving bottles available at the start and finish.

  • No results will be posted on site. Results will be posted to our website after the event.

  • Online pre-event beginner information. While you are welcome to ask questions at the event, we will not gather people together for beginner instruction.

  • Please do not attend if you are sick. Refunds will be made if you prepay and cannot attend.

Liability Waiver - Everyone must have a waiver on file. The registration system gives you an opportunity to accept the waiver for yourself or your family members. Minors whose registration is not handled by a parent/guardian must print out the form and bring it with them with a parent/guardian signature.

Pre-registration is now open and will close on Thursday, September 28 at midnight.
