Lake Haigler 12-Hour in Fort Mill, SC
The Lake Haigler 12-Hour is scheduled for November 21, 2026 at the ASC Greenway near Lake Haigler in Fort Mill, South Carolina. The event is organized by Mill Stone and is located at 2573 Lake Haigler Drive.
The race is contested on a roughly 5K loop that runs around and near Lake Haigler. Participants complete as many laps as they can within the 12 hour format. An aid station will be set up at the loop start and finish, stocked with typical ultramarathon supplies.
The event has a very limited capacity. There will be no camping allowed at the Greenway after the event, and all attendees must leave the site once the event concludes. Swag for the 2026 race is to be determined.
Organizers note that GPS devices may direct users to a different ASC Greenway location; entrants should use the provided map and the Lake Haigler entrance on Highway 21 for accurate directions. Visit the organization's website for the most recent information.
