Seward Solstice Run
Participants complete a 4.2-mile or 10k loop through the old-growth forest of Seward Park, passing towering Douglas firs and Western red cedars along Lake Washington. The route follows a wide main path before turning onto narrower, twisting trails with roots and small fallen logs to navigate. Runners can also take part in a themed costume contest celebrating celestial and sparkling attire.
