Kewash Marathon

The Kewash Marathon, held in Washington, Iowa, is an annual running event featuring a marathon, half marathon, 10K, and 5K races. In 2026, the event will debut the full marathon distance along the scenic Kewash Trail, known for its fast, non-technical out-and-back course with gradual inclines, declines, and flat stretches, suitable for runners of all levels. Participants receive a race shirt, finisher medal, post-race drink ticket (for those 21+), and free race photos.

The race starts and finishes at the YMCA of Washington County, offering a supportive and enjoyable atmosphere for both competitive and recreational runners. Visit the organization's website for the most recent information.
