I have been planning, much like you, to ride trail last fall, the spring of 2010 and the fall of 2009, but it never happened. The only time I have significant free time is in the heat of the summer and I may just do it in July this year.
My plan is to do a round trip. I like the trail enough that riding it both ways isn't going to be boring. It eliminates the need for a shuttle. I don't think I could do a century these days so my trip will be four days with Cedartown(twice) and Jacksonville as the stops. Eateries don't look great in Cedartown, but I hope for a surprise.
Four 50 miles days will be a challenge for my level of riding, but it won't leave me in pain.
Good luck getting your ride in this year!
