Kewash Marathon, Half Marathon, 10K & 5K

Lace up for the inaugural Kewash Marathon, joining the established Half Marathon, 10K, and 5K races on April 25, 2026, in Washington, IA. This highly-anticipated event marks the debut of the full 26.2-mile distance, offering runners a unique opportunity to be among the first to conquer this new course. Starting and finishing just off the historic town square at 207 W Main St., all distances traverse the scenic Kewash Nature Trail, a beloved former railroad bed known for its picturesque blend of woodland and prairie.

The course is celebrated for being fast, non-technical, and generally flat, featuring gentle inclines and declines punctuated by level stretches, making it welcoming for both seasoned runners and first-timers. While beginning on paved city streets, the majority of the route transitions to a crushed limestone surface, offering a varied and engaging experience. Runners will enjoy breathtaking views of rural landscapes, including wooded areas, open fields, and notable landmarks like Willow Pond, Hayes Timber, and the iconic Crooked Creek Bridge, all rich with wildlife and wildflowers. Typical race day conditions in late April bring pleasant highs around 64°F and lows around 40°F, with a modest 16% chance of precipitation, providing ideal running weather.

Beyond the beautiful scenery and accommodating terrain, the Kewash Marathon, Half Marathon, 10K & 5K boasts a reputation as a friendly and well-organized, community-supported event. Aid stations stocked with water and Gatorade are available, though runners are encouraged to bring their preferred gels or chews. Pacers are provided for the half marathon, and all finishers receive a custom medal. The festive atmosphere continues post-race with a party featuring food trucks, music, games, and a complimentary beer ticket for participants 21 and over. With free race photos and cash prizes for top finishers and course records, the Kewash Marathon promises an unforgettable running experience in the heart of Iowa.
