John ... Closer to home is the James River Park System. (Closer to my home, at least), The Buttermilk and Northbank trails form a loop around the James, bracketed on one end by Belle Isle and the other by the Nickel Bridge. Really good long hike. Not too technical and the elevation changes are very minor. But it's definitely single track and you won't believe you're in the middle of urban Richmond.
If you start at the bridge, take an extension into the bottom, grab some lunch, and continue the loop! Or hoof over to Rockets Landing. Both have decent restaurants.
Oh, and if you do Humpback, I've got a great restaurant just a few miles away for afterwards. (Can you tell that eating is as much a part of hiking to us? LOL!)
