I've done BRAT, the Bicycle Ride Across Tennessee, a couple of times and would really like to do it again. The name is a misnomer. Each year, the Tennessee Department of the Environment picks an area of Tennessee--Western, Middle or Eastern--and the tour does a big loop. Most of the overnights are in state parks. The tour itself attracts a smaller crowd and, so, it doesn't have the same party atmosphere as some of bike tours--like RAGBRAI. For me, this is a plus, but it may not be what you're looking for. BRAT is always in September. The weather is still typically warm by midday, but mornings and nights can be cool. The support is generally pretty good. The routes are well marked and the meals are plentiful and tasty (assuming they use the same caterer). The roads in Tennessee are generally pretty nice and, of course, depending on the area, are hilly.
ETA: It looks like this year's BRAT starts in Crossville, TN. That's a really pretty part of the state. My guess is that the ride will ride over and around (multiple times?) the Cumberland Plateau, so you're looking at some good climbing. That will be a really great tour. We have plans to go to Maine in September, but boy; I'd really like to do this one.

Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
