The scenery of Puget Sound has built a community of outdoor recreation over the years. Cities all over the area have been running yearly marathons throughout the years, with new runs cropping up in recent years.

From within the city of Seattle to the scenic routes on Whidbey Island and full marathons to kids’ runs, there’s an event for locals and visitors alike. This article will highlight 10 marathons in the Puget Sound, where to find them, how long they are, and more.

Seattle Marathon

Known as one of the biggest runs in the Puget Sound, the Seattle Marathon is a non-profit organization that has run both summer and fall events since 1970. Over the decades, the Seattle Marathon has grown into one of the largest mass-participation runs in the entire Pacific Northwest, resulting in it being ranked as the Runner’s Choice Best Marathon in Washington State.

The Seattle Marathon has events in multiple lengths, including half and full marathons, 5 and 10K runs, and kids’ events. They even have a marathon dedicated specifically to kids as young as kindergarteners. Participants can choose between running or walking and there are even virtual races. Additionally, the Seattle Marathon counts as a Boston Qualifier, making it a great run for both serious and casual runners alike.

Seattle Ghost Marathon

The Seattle Ghost Marathon takes runners from the Ferdinand Boat Launch in Seattle through Seward Park during the fall.

Aid stations are placed throughout the race to keep runners hydrated while the finish line is stocked with cold and hot drinks, as well as snacks, hot soup, chili, and hot dogs. 

This marathon is best known for its consistent support and dedicated mission of feeding the needy.

Their partnership with NW Ultras has provided food and blankets to the needy for over 5 years.

Capital City Marathon

This event hosts multiple runs, including a half marathon, a full marathon, a 5 mile run, and a kids’ run.

This 2 day event has 3 different races runners can participate in. Their marathon and half marathon races will take runners through Point Defiance Park’s gardens and forests, across the city’s Narrows Bridge, and eventually to the waterfront at the Dune Peninsula Park where the half marathon ends. 

The marathon will then continue down the waterfront and eventually turn around near the Museum of Glass. Once the race is completed, participants can enjoy the stunning views and the recreation center at Commencement Bay. The full marathon course counts as Boston Qualifier and is USATF-Certified.

Over time, the Grand Ridge Evergreen Trail Run has expanded to include a free kid’s race on their own separate gravel trail so local families can fully participate in the event. Additionally, the Evergreen Trail Runs are committed to reducing waste and welcoming participants of all walks of life, making it one of the most environmentally conscious races in the state.

The Grand Ridge Evergreen Trail Run is the finale event for Evergreen Trail Runs every year.

Snohomish River Run’s half marathon and full marathon cover a stretch of land alongside the Snohomish River itself, truly keeping in theme with the race’s name. The full marathon stretches onwards to the north all the way to Everett.
