This is an 84-mile towpath trail running through the heart of the Ohio & Erie Canalway. The Towpath’s northernmost trailhead is located just east of the intersection of Jennings and Harvard Ave West, about 5 miles south of downtown. From here, this mainly gravel path travels south into the heart of Cuyahoga Valley National Park. Along the trail, there are historic buildings, museums, pleasant villages, restaurants, pubs, and wildlife. The attached map has details on distance segments.
Within Cuyahoga Valley National Park, a convenient location to join the trail is the Lock 39 trailhead on Rockside Road. One special aspect of the trail in the National Park is that the Cuyahoga Valley Scenic Railroad runs alongside, so you can run one-way and then return via the the CVSR. Our map has the mileage between key distance points.
Another good running highlight in Cuyahoga Valley National Park is the Plateau Trail, which is a 4.4 mile loop and a 300-foot elevation gain. Starting point is near Peninsula, Ohio.
