We will have limited parking at the Blue Sky trailhead for full carpools on a first-come first-serve basis. Parking for all other participants and spectators will be located in the marina parking lot off of Shoreline Drive.

Race participants will not be required to pay the park day use fee.

**Parking is not allowed anywhere on 38E, along Shoreline Drive, or on any connecting residential street.**

Spectator Information

Much of the course is run on trails that are not easily accessible to spectators.

The best viewing points will be the Start/Finish line at the Blue Sky Trailhead, the Soderberg Trailhead, and the Hunter Loop turn around.

  • For the Start/Finish, park in the marina parking area (see above) and walk over, please DO NOT drive through or park at the Start/Finish.
  • To access the Soderberg Trailhead, continue North on Shoreline drive and make a left into the trailhead parking lot. If the parking lot is full, you may park in the marina parking area and walk north through the campground to the trailhead.
  • To access the Hunter loop (turn around), drive to the Devils Backbone parking lot near Loveland. Take Highway 34 West from Loveland and take a right onto Hidden Valley Rd and follow signs to the Devils Backbone parking lot. Follow the trail North up the hill to the junction of the Wild and Hunter loops.

While the entire trail system is open to the public, due to the high volume of traffic on the course we ask that friends and family refrain from hiking or biking further onto the course. Crewing and pacing by foot or by bike is not allowed and will result in the disqualification of your runner.
