Redmond Harvest Half Marathon

Harvest the fruits of your training at the Redmond Harvest Half Marathon, to be held Labor Day Monday (September 7, 2026)! Starting from the Redmond Town Center (new for 2026!), the Harvest Half is a fast, flat out-and-back half-marathon that does a short loop around town before going out-and-back north on the Sammamish River Trail. Whether this is your first half-marathon, or you are experienced with this distance, this 13.1-mile course will give you an opportunity for your running goals to come to fruition. Come support a local, all volunteer-organized race put on by Lake Sammamish Run Club and Seattle United Runners and finish your summer with a bang.
