Course Description

Celebrate the 10th annual Kewash Half Marathon, offering a perfect distance for every runner with a 5K, 10K, and Half Marathon. The USATF certified race course, with Certification Code IA1005MF, unfolds along the scenic Kewash Nature Trail, a former railroad bed stretching nearly 14 miles between Keota and Washington.
