Redmond Harvest Half Marathon

The Redmond Harvest Half Marathon is a local 13.1-mile race starting and finishing in Marymoor Park, Redmond, Washington. It takes place on Labor Day Monday, following a fast, flat, paved out-and-back course instead of a hilly road route. Lake Sammamish Run Club and Seattle United Runners organize it, catering to both first-time half-marathoners and those aiming for a quick time. From Marymoor Park, the course heads west, turns north onto the Sammamish River Trail, and then returns the same way to the start. The flat trail course allows for straightforward pacing, attracting competitive runners alongside local participants using it as a late-summer goal race. The event hosts the PNTF Road Championship, provides on-course support, and concludes with a catered afterparty.
