Georgia Ultrarunning & Trailrunning Society holds races of various distances throughout Georgia, from the Red Top Rumble 11.5 Mile Trail Run in February to Mystery Mountain in the fall to the Pine Mountain Trail Runs in December. We also have group training runs and the eagerly anticipated GUTS End of Year (EOY) party, er, meeting! See our GUTS membership information 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?!?!
