FATS 50K

FATS 50K Race is held the first sunday of November annually on the Forks Area Trail System in South Carolina. The course is fast yet very challenging.

The FATS 50K and Half Marathon trail race is held on the Forks Area Trail System (FATS) on the first Sunday in October every year. The location is in Clarks Hill, SC just outside of North Augusta, SC. Runners will navigate mostly single-track trails with a few rolling hills. Runners will encounter rocks, roots, and the occasional mud along the trails and be treated with a few scenic views of the

Savannah River. The race starts and finishes at the South trail head. The cut-off time is very generous, usually around 10 hours based on how much daylight we have that time of year. FATS 50K is a perfect trail race for your first ultra marathon and if you have never raced on a trail the FATS Half Marathon is a blast! Nathan Maxwell

FATS 50K wouldn’t be possible without volunteers. If you are not running this year, we would love your help at an aid station or packet pickup. Every volunteer gets a FATS volunteer shirt, we think they’re pretty cool. Sign up to volunteer at https://ultrasignup.com/register.aspx?did=140180 if you want to join the team on November 1

No cups. No crab, imitation or otherwise. No shortcuts, no matter how good Skinny looks from the side trail. No complaining about roots and rocks, that's just a normal Tuesday at FATS. No skipping the PB&Js, they're basically a course requirement.
