Redmond Harvest Half Marathon

The Redmond Harvest Half Marathon takes place on Labor Day Monday at Marymoor Park in Redmond, Washington. The event features a single distance for participants:

  • Half Marathon (13.1 miles)

The course is designed as a fast and flat out-and-back route. It begins at Marymoor Park, heads west out of the park, and then proceeds north along the Sammamish River Trail before returning to the original starting location. This event is organized by the Lake Sammamish Run Club and Seattle United Runners.

Participants who are members of an organized club have the option to participate in the NW Club Championship. To join this competition, runners select a specific club team during the registration process. Performance in this category contributes to the overall team standing. Registration for the event opens in January and closes at the beginning of August. Visit the organization's website for the most recent information.
