Runners follow an out-and-back course for Waterloo’s Park to Park Half Marathon, which starts and finishes inside George Wyth State Park along Wyth Road, near Fisher Lake. From there, the course unfolds along the roads that wind through the park as well as several miles of the Cedar Valley Lakes Trail, the paved running, walking and biking trail that stretches more than 100 miles between the cities of Cedar Falls, Waterloo, Hudson and Evansdale.
