BE PART OF THE LEGION OF BLOOM! Come run, walk, stroll, or crawl with us through Seward Park and along South Lake Washington Boulevard, surrounded by the breathtaking beauty of cherry blossoms.
2026 will offer 5K, 10K, and Half-Marathon runs! All runs will extend onto Lake Washington Blvd to take in the blossoms along the outer stretch of the park.
We are happy to announce this year we will have parking options available within the park!
Cross the finish line under our signature inflatable arch and celebrate spring in full bloom!
