I'm not involved in the Georgia Marathon, but I've talked to Gary and he told me the plans are to run the event exactly as it was ran last year, with the tournament starting in Statesboro, and the final four of eight tournaments taking place near Atlanta.
December 26: Statesboro, GA
December 27: Macon, GA
December 28: Newnan, GA
December 29: Franklin, GA
December 30-Jan 2: Atlanta area
These are just the projected dates I've heard so don't make any travel arrangements yet!
