This is a "Rail-Trail". Took the family for a ride on Sunday. I was disappointed. The path is uneven and bumpy and the shade and mottled light makes the bumps invisible. Starting in Bedford and running East toward Lexington is a waste of time due to the many road crossings. I would suggest one starts in Lexington, and just forget about the western section to Bedford. Running East has a slight uphill grade which one doesn't realized until you come back west, then it's a nice downhill roll. This is a very shaded trail with poor visibility, so I would suggest using my flashing strobe so people can see me coming in advance and move aside. I don't plan on going back to this trail - is has lots of walkers.
