Georgia Ultrarunning and Trailrunning Society (GUTS) is a fun-loving group of runners that holds races of various distances in Georgia, from the Red Top Rumble 11.5 Mile Trail Run in February to the Mystery Mountain Marathon in October. We also have group training runs, a yearly camping weekend, and the eagerly anticipated GUTS End of Year (EOY) party, er, meeting! See our Join GUTS membership link above. It’s easy, it’s cheap, and it’s worth it. After all, don’t you want to have GUTS for the Atlanta Fat Ass?!?!
