Mill Stone 50k

Fort Mill, United States • 7 Feb 2026

Event overview

The Mill Stone 50K is an off-road race held at the ASC Greenway in Fort Mill, SC. The event offers two distances:

  • 50K
  • 10M

The 50K is run as three loops of the same course. The 10M uses one loop of that course and runs concurrently with the 50K. Overall male and female awards will be given for both distances. 50K finishers receive a custom medal made by a local artist. All participants receive a race shirt.

Course and race logistics

The course is mostly single-track, technical trail with some gravel road and dirt trail in a private green space in the suburban Charlotte area. There are at least two creek crossings, and sections may be muddy. The course may be adjusted due to trail changes, storm damage, or downed trees. A landmark called the Mill Stone sits along the loop; runners are strongly encouraged to touch it as they pass.

Aid stations are located roughly at the 4- and 8-mile markers and at the start/finish and will supply typical ultra food and fluids. Runners are asked to carry at least one water bottle. Course maps are provided on Caltopo and have been updated to reflect new bridge changes planned for June 2025.

Registration and policies

Registration closes February 4, 2026. Pricing for 2025 is listed as $90 (rising later to $105) for the 50K and $55 (rising later to $75) for the 10M; shown prices include taxes and fees. Shirt orders are placed in early January, and a mid-January deadline applies to guarantee sizes. There are no refunds, transfers, or deferrals. The event is held rain or shine, though severe conditions may prompt contingency plans or a makeup date. Visit the organization's website for the most recent information.
