80 Miles – 15 Legs – 1 Epic Day

Beat the February funk in the greenest corner of the lower 48


You and your best road and trail running buddies. Form a team of 3 or 5 people—any mix of age, gender, and ability, as long as your team can average a 12-minute pace or faster. Load up your team van with food, drinks, extra layers, tunes, and a fun competitive spirit.


Saturday, February 23, 2019. Wave starts at 6:00, 6:30, and 7:00 a.m., based on teams’ projected average pace. Teams are also asked to attend the Friday evening packet pickup/rules and safety briefing (place/time TBD).


The Olympic Peninsula in Washington state. Frosty Moss HQ is based in Port Angeles, where the mountains greet the sea. The course follows the Olympic Discovery Trail AND the Adventure Route.

Pavement + Trail = The Best of Both Running Worlds

Finally, you don’t have to choose between your roadie and trail friends. Join forces and crush the competition on pavement and dirt!

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 consists of 15 legs in a mix of distances (3.2 to 10 miles) 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

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

Along the way, you’ll experience the best of the Olympic Peninsula:

  • Towering evergreens and vivid green moss and ferns
  • Sol Duc River, Lake Crescent, and the Strait of Juan de Fuca
  • Olympic National Park and the Spruce Railroad Trail
  • Views of the Olympic Mountains to the south and Vancouver Island to the north
  • The wild and free Elwha River
  • Miles of waterfront in Port Angeles
  • Bucolic farmland in Sequim
  • The restored Dungeness River Railroad Bridge
  • The iconic architecture of the Jamestown S’Klallam Tribe

In addition to an epic outdoor experience in the far northwest corner, all runners receive…

  • Swag bag chock-full of Frosty Moss Relay goodies and other surprises
  • Comprehensive event guide, fully marked 80-mile course, and on-course race support.
  • After-party at Club 7 in the Jametown S’Klallam Tribe’s 7 Cedars Casino, with meal, beverages, music, awards, and raffle prizes.
  • Bragging rights for getting after it all day on the Olympic Peninsula in February.

Relay teams provide their own vehicle and should be self-sufficient with food and water. Aid stations and sanicans will be stationed at a few points along the course, but teams should not rely on them as their sole source of support.


All roads will be open—traffic rules apply. Runners must stop and wait for traffic before crossing intersections.


Teams must average an overall 12-minute mile pace or faster, including time spent at exchange points. For everyone’s safety, teams that reach the exchange point at Railroad Bridge Park (end of leg 12) after 8:30pm will receive a “Go Directly to the Finish Line Party” pass (aka DNF). No exceptions! Organizers may pull teams off the course at other points at their discretion.

    • The 2019 event is limited to a total of 50 teams.
    • 3-person team: $255 until December 31, 2018; $300 January 1 to February 21, 2019.
    • 5-person team: $425 until December 31, 2018; $500 January 1 to February 21, 2019.
    • NOTE: When you register, you’ll need to estimate your team’s overall average pace, including time spent at exchange points. This determines your start time. Teams reaching the end of Leg 12 after 8:30pm will be directed to the finish line.
      Wave 1, 6:00 a.m. start: Team average pace 10-12 minute miles.
      Wave 2, 6:30 a.m. start: Team average pace 8-10 minute miles
      Wave 3, 7:00 a.m. start: Team average pace 6-8 minute miles.
    • Registration ends at midnight PST 2/21/19. No on-site registration.
Team Meeting/Packet Pickup: Friday, February 22

Teams should plan to attend the Friday evening packet pickup/rules and safety briefing (place/time TBD). There will be on-site check-in on Saturday, but be aware that the drive from Port Angeles to the start line takes about an hour. Stay in the area the night before if at all possible.

PRO TIP: Register early to hold your spot!

You don’t need to know the names of everyone on your team when you register. Your team captain will enter their contact info, the team’s name, if it’s a 3- or 5-runner team, and wave time based on overall average pace. On relay weekend, bring:

  • A team roster—this is where you’ll need to know who’s on your team.
  • Signed liability waivers for every member of your team.
  • Both forms are linked in the top menu bar of this website.

Yep, you’ll probably be running in the dark at some point. Runners must wear reflective vests, headlamps, and blinky lights when the light dims and at all times along roadways. Some parts of the course can also be dark due to the dense forest. Bonus dark: The unlit restored train tunnel on Leg 3.

February weather on the peninsula can change by the minute and the microclimate. Be prepared for sun, rain, flurries, drizzle, rainbows, mist, clouds, and, of course, frost.

Temperatures range from the high 20s to high 40s depending on terrain, elevation, and microclimate. Be prepared with appropriate layers, plus warm blankets and beverages in your team vehicle. Typically, weather is wetter on the west end and gets warmer and drier as you move east into the rain shadow. That said, be ready for anything, anytime, anywhere.

Bright side: Prevailing west winds off the Strait of Juan de Fuca mean a high chance of a tailwind!
