Atlanta Fat Ass 50K

Join us for the annual Atlanta FatAss, providing low-key, post holiday fun since 1994. Burn off those holiday pounds & run more than anyone has the right to enjoy! Please remember: no wimps, no fees, no problem! While this is a FatAss event, there will be plenty of aid station fare to keep you going.

GUTS Members Only!

This is a GUTS event and is FREE, but is only open to 2025 GUTS members. Membership will open on November 3rd on Ultrasignup - GetGUTS

Course

The course is 6 loops on the WHITE trails (counter-clockwise/down Jack's and up the stairs).  The trail can be technical in some spots (think roots, rocks, boulders). Poles are allowed but most people do not use them.The course will be very well marked with bright tape/flags.

Start/Finish will be at the Group Shelter. CUTOFF: Runners must start the final loop by 3:00 PM.

FatAss Crockpot Chili Contest

Bring your best chili and vie for a years worth of bragging rights! Please bring the chili in a crockpot because we don't have enough burners on the stove for everyone. GUTS will provide the bowls and utensils as well some yummy chili toppings. Each runner will be given a ballot to vote for their favorite chili. The more chili you bring - the more post-race food we will have. Read that again: The chili that you bring IS the post-race food!
