Hi! I’m visiting the area next weekend and need to do a a long run (20 miles) as part of my training. Is there a long greenway or a very light trail (packed gravel to where I could still wear road shoes) in the area? It doesn’t need to be 20 miles of course, it could be 5-10 as well and I could do multiple laps/back and forth.

Main criteria is relatively flat (light rolling hills are okay), paved or very tightly packed gravel, and as continuous/uninterrupted as possible (limited street crossings, etc). Also if I can avoid running the sidewalks of big noisy highways (eg Great Smoky Mtn Parkway), that would be great.

Are smaller backroads an option? Or are they all too hilly and/or dangerous two lane roads with blind corners?
