About the race
The Mill Stone 50K is a challenging trail ultramarathon held at the scenic Anne Springs Close (ASC) Greenway in Fort Mill, South Carolina. The race features three 10.5-mile loops of mostly single-track, technical trails with some gravel and dirt paths, including at least two creek crossings. The course is known for its rugged terrain and potential mud, offering a tough experience for runners.
The event also includes a 10-mile race using one loop of the same course. Participants receive race swag and awards, with the 50K finishers earning custom medals. The race is organized by Rock Hill Striders and emphasizes safety, volunteer support, and a strong community atmosphere. Visit the organization's website for the most recent information.
