Frosty Moss Relay runners trace the Olympic Discovery Trail (paved multiuse path) and Adventure Route (singletrack trail) from west to east, beginning at the Camp Creek Trailhead along the Sol Duc River and finishing in Blyn at the Jamestown S’Klallam Tribe facilities.

Frosty Moss Relay is about 80 miles and consists of 15 legs in a mix of distances on pavement and trail. Paved legs are mostly on former railroad grade, meaning relatively flat with some rolling hills. The Adventure Route is hilly dirt singletrack, not overly technical, plus a few miles of gravel road at the beginning. Full Moss teams have 2 – 5 runners.

The 30-mile Mini Moss has 8 legs and teams of 2, 3, or 4 runners. It begins at the end of Ediz Hook in Port Angeles and follows the Olympic Discovery Trail to Blyn. All pavement, no trail running.

Teams are welcome to divide the legs among runners as they like, but a runner may not run back-to-back legs.
