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. You'll chase PRs, friends, and that runner's high on one of Seattle's most beautiful routes. Timing will include mile splits, live tracking and printed finisher cards.
Cross the finish line and claim your super comfy long sleeve shirt, finisher medal, and FREE professional race photos (because if it's not documented, did it even happen?).
The pain fades. The photos last forever. The bragging rights? Those are eternal.
