Lake Haigler 12 Hour : Fort Mill, SC
The Lake Haigler 12 Hour is a timed endurance event held on November 21, 2026, at the ASC Greenway in Fort Mill, South Carolina. Runners complete repeated laps of a roughly 5K loop around and near Lake Haigler. The course uses a looped route with the aid station positioned at the loop start and finish, offering typical ultra race supplies.
The event is being organized with a very limited participant capacity. Registration closes on Thursday, November 19, 2026. Swag for the 2026 race has not been determined.
Camping will not be allowed after the event; all runners, crew, and spectators are required to leave the Greenway after the event concludes. Organizers note that standard check in and bib pickup procedures are used, and that all laps must be completed by the published cutoff to count.
The Lake Haigler entrance for the ASC Greenway is on Highway 21 north of Fort Mill. Event directions advise caution when using GPS because some devices direct users to a different ASC Greenway location that is a substantial distance from the race site. From I 77, take Exit 85 toward Fort Mill and follow local signage to the Lake Haigler entrance. Visit the organization's website for the most recent information.
