On the southern side of the Tennessee River near downtown, Fort Dickerson Park is built around a well-preserved earthen fort from the Civil War and a quarry lake. There are four miles of multi-use trails that are popular for running, on mainly wooded terrain, with some sections skirting around the quarry. It’s ~2 miles around the perimeter. Can also connect to Mary Vestal Park, using W. Blount Ave., which adds another ~1 mile of trails. In all, one can put together a nice, ~5 mile run! Note: this is part of an expanding, 1,000-acre ‘urban trails’ system, which is undergoing continual improvement!
Add-Ons: Connect to other nearby parks and trails. High Ground Park and Scottish Pike Park is just west. Can also take the Henley St. Bridge (busy, but a wide, runnable sidewalk) to cross the river and run along the Neyland Greenway and the other, numerous trails on the north side.
