From the organizer

Spring has never felt this good.

Join hundreds of runners for Seattle’s most iconic 10K and 10-mile loop around Lake Union. This isn’t just a run—it’s a celebration of everything that makes our city incredible.

Start and finish at Gas Works Park. Cruise past Lake Union Park. Wave to the Space Needle. Conquer the Fremont Bridge.

Chase a PR, run with friends, or just soak it all in—this is one of Seattle’s most scenic and energizing race experiences.
