Has anyone ever done this ride? If so, how is it for a beginner/NTPer?
I've done the 46 miles North to Gettysburg, starting in Thurmont, and I remember that the beginning is pretty flat and then rollers the rest of the way. Did you do Columbia course last week? I haven't done the 23 miles route, but it is listed as a difficulty of 3, so I'm guessing it is probably comparable to Columbia (maybe a little easier) BUT with much less traffic.
It is a hike up 270 to get there but I thought the ride was worth it.
