80 Miles – 15 Legs – Teams of 3 or 5 Runners

Pavement and trail running in the greenest corner of the lower 48


You and your best road and trail running buddies. Form a team of 2-5 people (Full Moss) or 2-4 people (Mini Moss)—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, April 6, 2019. Wave starts at 6:00 and 8:00 a.m., based on teams’ projected average pace. Team captains are also asked to attend the Friday evening packet pickup/rules & safety briefing: 6pm at Barhop Brewing & Pizza in Port Angeles.


The North 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!

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 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. Teams are limited to ONE on-course vehicle, ideally a van, minivan, or SUV. No motorhomes, limos, buses, or tow-behind trailers. Decorate your ride! Frosty Moss Race Directors will give an award to one creative team for “Best Team Vehicle”.


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


This is a challenging event! Teams must average an overall 12-minute mile pace or faster, including time spent at exchange points. That said, 12-minute teams may very well find themselves missing the cutoff. Grab a fast friend as your ringer. 

Frosty Moss Teams must reach the end of Leg 7 by 4:00 p.m. If your team does not arrive in time, you are required to skip the next race leg, and start again at the start of Leg 9 at Port Angeles Yacht Club. 

Frosty Moss Teams reaching the end of Leg 12 (Railroad Bridge Park) after 8:00 p.m. will be sent directly to the finish line. Teams farther behind will also be sent to the finish line when they reach the end of their leg. In these cases, teams will receive a DNF (no race time) but are encouraged to hit the party time to celebrate your mossy adventure.

Mini Moss Teams reaching the end of Leg 5 (Railroad Bridge Park) after 6:30 p.m. will be required to skip the next race leg, and start again at the start of Leg 7 at Carrie Blake Park.

Organizers at their discretion may also pull teams off the course sooner or direct teams to skip a leg(s) to make the cutoff.

    • The 2019 event is limited to a total of 50 teams.
    • 3-person team: $255 until April 5, 2019. December 31, 2018; $300 January 1 to February 21, 2019.
    • 5-person team: $425 until April 5, 2019. 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 8:00pm will be directed to the finish line.
      Wave 1, 6:00 a.m. start: Team average pace 10-to-12-minute miles.
      Wave 2, 8:00 a.m. start: Team average pace faster than 10-minute miles
    • Registration ends at midnight PST 4/5/19. No on-site registration.
Team Meeting/Packet Pickup: Friday, April 5

Team captains should plan to attend the Friday evening packet pickup/rules and safety briefing: 6pm, Barhop Brewing & Pizza, Port Angeles. 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 will be running in the dark at some point. Runners must wear reflective vests, headlamps, and blinky lights when the light dims. Some parts of the course can also be dark due to the dense forest. Bonus dark: The unlit restored train tunnel on Leg 3.

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.

April temperatures range from the low 40s to mid 50s 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!
