Lake Haigler 12-Hour - Fort Mill, SC
The Lake Haigler 12-Hour is scheduled for November 21, 2026 at the ASC Greenway in Fort Mill, SC. The event is a timed 12 hour race run on a loop course of approximately 5K that circles and runs near Lake Haigler. Laps completed on the loop count toward each participant's total distance.
The course will feature an aid station at the loop start and finish offering customary ultra race support. The event has a very limited capacity. Swag for the 2026 race is to be determined.
There will be no camping on the Greenway after the race; all runners, crew, and spectators must leave the site after the event. Organizers note that the Lake Haigler entrance for the ASC Greenway is on Highway 21 north of Fort Mill and that map-based directions should be followed rather than relying solely on GPS, which may point to a different ASC Greenway location.
The event is organized by Mill Stone. Registration availability and official entry details are listed through the event's registration channels. Visit the organization's website for the most recent information.
