Course Rules

Course Rules
  • Although these races take place on maintained trails, each race will encounter uneven/rocky terrain. You must be willing and able to navigate trails with changing weather and/or conditions. Each course will have multiple aid stations at the racers disposal that are equipped with water, snacks, first aid, and medical personnel. 

  • There will be no pacers for any race.

  • We love spectators and encourage family/friends to cheer their people on from the start/finish line only. Due to the nature of the courses and limited parking, please do not drive and park anywhere along Ousel Falls road or Aspen Leaf Drive. We will have runners and aid stations crews moving on these roads.

  • We ask that the public refrain from using BSCO trails until after all races are finished at approximately 12:00pm.

  • Runners are responsible for their own behavior and actions of their spectators. 

  • There are no refunds allowed for this race for any reason. If you are signed up for a race currently and wish to drop down to a shorter distance or team event, you may do so before July 12th in Runsignup. There will be no refunds for changing distance or event.

  • We love dogs but you may not run with a dog (even on leash) for any race due to the nature of the courses and the safety of all runners. All dogs must remain on leash at the start/finish line and please pick up after your pet.
