Lake Sammamish Half Marathon

The Lake Sammamish Half Marathon is a point-to-point running event in Redmond, Washington. The course follows a fully paved interurban trail from Marymoor Park in Redmond to Lake Sammamish State Park in Issaquah, delivering a flat, fast route ideal for personal bests. The race offers a Half Marathon and a Virtual Half Marathon, plus a Half Marathon Walk with a four-hour time limit.

It’s chip-timed, and each participant receives a custom bib, shirt, and finisher medal. Aid stations provide Clif gels, Nuun and water. The finish is by the lake with food and music; the course is cupless, so plan hydration accordingly. Visit the organization's website for the most recent information.
