Dirt track is more along the lines of what I was thinking of than a trail. Something like the road that goes around your local reservoir or the perimeter of a golf course that's open to the public. Boyd is right singletrack trails and rough fire roads invite injury to the ankles if your not used to it. Now is always the best time to begin working toward a goal. Starting tomorrow only serves to give you one day less to prepare.
