The Sweetwater River Trail includes a little bit of everything: singletrack, double-track, paved trails, dirt trails, bridges, boardwalks and everything in between. This is a great trail to run whether you are a seasoned runner or new to the sport. It isn't too steep (for the most part), and it follows along the river with some shade at times.
