Welcome to the Green Season

Towering evergreens. Endless moss and ferns. Miles of waterfront. Snowcapped mountains. Need a cure for gray-season blues? Frosty Moss has you covered.

Pavement + Trail Runners Unite

From the Sol Duc River to Blyn, the 80-mile course follows the paved Olympic Discovery Trail and the singletrack Adventure Route. The 30-mile Mini Moss begins at Ediz Hook.

Celebrate After the Race

As if your day wasn’t epic enough, 7 Cedars Resort is ready to help you celebrate. They will host hot food, cold drinks, awards and fun after Frosty Moss Relay

Leg 3: Lake Crescent, Olympic National Park

Run through the restored McPhee Tunnel.
Trust us: Take the quick detour for the view from the bridge over Devil’s Punchbowl.

Legs 4–6: Adventure Route

Pavement gives way to 25 miles of trail running. Think dense forest opening up to big views of the Olympics, the Strait of Juan de Fuca, and Canada.

Leg 7: Elwha River Bridge

Run across the wild and free Elwha River on the Olympic Discovery Trail’s suspended pathway.

Leg 12: Dungeness River Bridge

Our Slugs Are a Pretty Big Deal

Foot for scale. This beast lives on Leg 4. Watch your step.

Frosty Moss 101: How Does a Relay Work?

1. Form a team: 2 – 5 runners (Full Moss) or 2 – 4 runners (Mini Moss).

2. Load up your team vehicle with food, drinks, extra layers, tunes, and teammates.

3. Drop off your first-leg runner at the start line. They run to the next leg’s starting point (aka the relay exchange).


4. Meanwhile, the rest of the team drives to the next relay exchange and waits for the runner.

5. Runner arrives at exchange, tags the next runner, who runs to the next exchange. Tired runner gets in van.

6. Repeat until the finish line!
