One of the most beautiful courses we've seen --- winding roads and bike paths through beautiful forests alongside small lakes. It's a double-loop but is so scenic that that's not an issue. Very well organized. Small (less than 100 marathoners, but a few hundred half-marathoners) very quiet, and almost no fan support, which some may prefer. An easy 85-minute drive from Atlanta. Temperatures were very cool---perfect for running.
Pacers available, good post-race food, sufficient aid stations (with Cerasport, and one with pickle juice!), and porta-potties on course.
Plentiful parking adjacent to start, very inexpensive lodging in Atlanta with AirBNB, flights to Atlanta from other major airports can be inexpensive.
Very well-organized race with rolling hills

2016 - A very well-organized race. Apparently, Callaway Gardens handed the event over to a new management company, because I did not experience any of the problems noted by past reviewers. The water stations were well-manned and well-stocked. Post-race snacks were plentiful, with the standard fruit, cookies, and even pizza. Not many spectators because it's basically a nature run, but the ones who happened along were enthusiastic. Weather was perfect - 32 degrees at the gun, 60 by the finish. I had a great time.
Rolling hills. Easy to go out too fast, but you want to save energy for the incline between miles 5-8 and 18-21.
Host hotel on property was a good deal, less than a mile from the start.

I'd call this just an average marathon. It is two loops around the Callaway Gardens resort in winter. It's a small race (~100) plus the half marathoners. Usually had to grab my own cups at the aid stations. The people didn't hand them out. I really did like that the awards are given as you finish - you don't have to wait around for everyone to be done.
There are some pretty short steep climbs on the course that will wear on you. Also, a good part of the race takes place on narrow bike trails. These trails are often uneven and very curvy. Take it easy the first couple of downhill miles - they are deceptively fast and you'll be cooked by the time you hit the hilly sections. Once you hit the turn around at miles ~9 and 22 (I think) it is downhill and flat to the halfway and finish.
