About the event

Experience the Atlanta FatAss, an iconic post-holiday tradition since 1994. This low-key yet exhilarating race offers runners the chance to burn off holiday pounds while tackling six grueling loops on the WHITE trails of the park. The course winds counter-clockwise down Jack's and up steep stairs, presenting technical challenges with roots, rocks, and boulders along the way. Poles are permitted but rarely used as most participants rely solely on their endurance.
Aid stations will be well-marked with bright tape and flags to guide runners through each loop until 3:00 PM when the final cutoff time arrives. The race is exclusive to GUTS members, who can register for free from November 1st on Ultrasignup - GetGUTS. T-shirts are available as an optional purchase during registration.
Adding a culinary twist to the event, participants are invited to bring their best crockpot chili to compete in the FatAss Crockpot Chili Contest. Bring enough chili to share and enjoy your creation as part of the post-race feast. GUTS will provide bowls, utensils, and toppings for this communal celebration.
Race day parking is available at a cost of $10 or with an annual Georgia State Park pass in the Group Shelter lot. Bib pickup begins at 7:00 AM at the same location, where you'll find detailed signs and volunteers to direct runners throughout the event.
Join fellow GUTS members for this unique blend of competition, community spirit, and hearty post-race food.
