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. Mini Moss begins at the end of Ediz Hook in Port Angeles (all pavement; no trail running).

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 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. 

The Frosty Moss 50K follows the same amazing route at the Mini Moss.

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

Packet Pickup: Friday, February 25

Team captains should plan to attend the Friday evening packet pickup, at 7 Cedars Resort. Bring a printed copy of your Team Roster. There will be on-site check-in on Saturday, but be aware that the drive from Port Angeles to the start line for the 80-mile Frosty Moss takes about an hour. Book lodging in the area the night before if at all possible.

PRO TIP: Register early to hold your spot!


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

  • Swag bag of Frosty Moss Relay goodies and other surprises.
  • Comprehensive event guide and on-course race support.
  • Meal, beverage, and awards at Jamestown S’Klallam Tribe’s 7 Cedars Resort.
  • ** 7 Cedars Resort banquet room guests must show proof of COVID-19 vaccination or proof of negative test within 72 hours for indoor dining. They will provide food To Go for those who are unvaccinated or do not have test results to show, and then you can dine on the patio, in your room, or take it with you.
  • Bragging rights for getting after it all day on the Olympic Peninsula in May.

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”.

50K runners must be dropped off and picked up – we do not have a shuttle service. 50K runners can have one support person/vehicle along the course.


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.

50K runners must reach the end of Leg 5 (Railroad Bridge Park) by 7:00 p.m. (14mm or faster pace)


You will be running in the dark in the morning and evening. 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.

Sunrise/Sunset in Port Angeles, WA, on 2/25/23:
Sunrise: 7:03 a.m.
Sunset: 5:52 p.m.
Day length: 10 hours 49 minutes


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.

Late-February tempertures typically range from upper 30s to mid 40s Fahrenheit, 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!
