We'd always heard this was a great place but had never tried it. Friends suggested we rent bikes at Silver Comet Cycles which is right on the trail - can't beat that as you get a first class bike with a helmet for $10/hr. So, off we went. The trail is about a car lane wide with a stripe down the center. We did about 9 miles in just over an hour. The trail is surrounded by trees so the ride is cool. Up hills, down hills, over large bridges, separated from everything by what appeared to be a minimum 50 yard barrier of trees and small brush. Very well marked distances and where the trail crossed roads, there were buttons to press that would stop traffic. We were there on a Monday afternoon and there was a steady flow of mostly bicycles with a few walkers on the trail. I'm told it is built on an old train bed and it goes from Smyrna to the Alabama line. This is the best I've ever seen to ride bikes for long distances.
