The Seattle Marathon Summer Event returns on Saturday, June 27, 2026 at the stunning Seward Park (5900 Lake Washington Blvd S, Seattle WA 98118) — a forested peninsula on Lake Washington with sweeping views of Mount Rainier on clear days. This annual family-friendly event offers four distances: Half Marathon (13.1 miles, 7:00 AM, $122.86), 5K (8:30 AM, $62.52), 10K (9:30 AM, $78.68), and the Kids Fun Run (1K sprint with goodies at the finish, 10:45 AM). A popular 15K Combo option lets runners tackle both the 5K and 10K (3 laps total around Seward Park). All courses loop around the Seward Park peninsula, offering continuous water views. Dogs on leash are welcome — a beloved signature of this event. Every participant receives a race shirt, bib, finisher medal, and refreshments at the finish line. Top 3 overall men, women & non-binary in the 5K (sub-25:00), 10K (sub-45:00), and Half Marathon (sub-1:30:00) receive awards. The event is rain or shine. Organizer: Seattle Marathon Association.
