About This Race
The FATS Trail Race stands as one of the Southeast's most enduring and beloved trail running events, having challenged runners for nearly two decades in the Forks Area Trail System within Sumter National Forest. This race epitomizes the technical, root-laden singletrack that makes the Carolina Piedmont region legendary among trail runners. The 2025 edition marks a Special Edition year, as the signature Deep Step trail remains closed, forcing organizers to reimagine the course while maintaining the race's distinctive character. The adjusted routes still deliver the rolling terrain, technical challenges, and relentless root networks that have made FATS a proving ground for runners seeking to test themselves against authentic Southeastern singletrack. With three distance options starting in quick succession on a November morning, FATS offers everything from a challenging introduction to trail racing with the 10K to a full ultra experience with the 50K. The race maintains its grassroots feel with solid aid station support and a community atmosphere that reflects the dedicated trail running culture of the region.
The 2025 Special Edition course adapts to the Deep Step trail closure while preserving the technical character that defines FATS. The 50K route emphasizes Great Wall, Skinny, and Brown Wave trails, finishing strong on Great Wall. These trails showcase classic Southeastern singletrack: rolling terrain punctuated by root gardens, rock sections, and the kind of technical features that demand constant attention from runners.
Both the half marathon and 10K follow updated routes that skip Deep Step while maintaining full distance integrity. The terrain remains true to the FATS experience with flowing singletrack interrupted by challenging technical sections, all woven through the mature hardwood forests of the Sumter National Forest in South Carolina.
