The Frosty Moss Relay, with 80-mile and 30-mile race courses for teams of two to five participants, is set for Saturday, Feb. 29.

The course primarily follows the Olympic Discovery Trail and Adventure 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.

The 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 single track, not overly technical, plus a few miles of gravel road at the beginning. Full Moss teams have two to five runners.

The 30-mile Mini Moss has eight legs and teams of two to four runners. Its course begins at the end of Ediz Hook in Port Angeles and follows the Olympic Discovery Trail to Blyn. The course is all pavement (no trail running).

Teams are welcome to divide the legs among runners as they like, but runners may not run back-to-back legs. Teams must average an overall 12-minute mile pace or faster, including time spent at exchange points.

Participants receive a swag bag, event guide, on-course support and an after-party at Club 7 in the Jamestown S’Klallam Tribe’s 7 Cedars Casino, with meal, beverages, music and awards.

Cost is $95 per person for the Frosty Moss (limit 60 teams) and $75 per person for the Mini Moss (limit 25 teams). Registration closes Feb. 27.

Packet pick-up is from 6-9 p.m. Friday, Feb. 28, at Barhop Brewing & Pizza in Port Angeles. Participants need to bring printed copies of one’s team roster and signed waivers for all teammates.

On race day, wave start times are based on teams’ projected average pace.
