Lake Sammamish Half Marathon

The Lake Sammamish Half Marathon offers runners an enjoyable journey on a fully paved, smooth trail from Marymoor Park in Redmond to Lake Sammamish State Park in Issaquah. Perfect for achieving a personal best, this flat race accommodates both runners and walkers with a generous time limit. Participants receive a custom bib, shirt, and finisher medal, with aid stations featuring Clif gels, Nuun, and water along the route. The finish line, located by the beach, promises food and music. The event is cupless, requiring competitors to carry their hydration or use a re-usable cup. Virtual participation is also available.
