Lake Haigler 12-Hour
The Lake Haigler 12-Hour takes place on November 21, 2026 at the ASC Greenway near Lake Haigler in Fort Mill, SC. The event is a 12-hour timed race conducted on a roughly 5 kilometer loop that runs around and near Lake Haigler.
The race course uses a 5K loop with an aid station located at the loop start and finish, offering the typical support items used at ultrarunning events. The field is very limited in size and the organizer notes restricted capacity for the event. Bib pickup and check-in will be available on race day. All laps must be completed before the official cutoff in order to be counted.
There will be no camping at the Greenway after the race this year; participants, crew, and spectators must clear the venue following event closure. The event is organized by Mill Stone. Registration availability is shown on the event offer and registration closes on November 19, 2026. Visit the organization's website for the most recent information.
