Lake Haigler 12-Hour

The Lake Haigler 12-Hour is a night trail running event held at the Anne Springs Close (ASC) Greenway in Fort Mill, South Carolina. Scheduled for the Saturday before Thanksgiving, the race features a 5K loop course around and near Lake Haigler. Participants run continuously from noon to midnight, aiming to complete as many laps as possible within the 12-hour time frame.

The course includes an aid station at the start/finish area, providing typical ultramarathon support. The event has a limited capacity to maintain an intimate atmosphere. Camping is not permitted after the race, and all attendees must leave the Greenway shortly after midnight. Visit the organization's website for the most recent information.
