The Lake Haigler 12-Hour Ultra Race, set to take place on November 21, 2026, offers runners an immersive experience along the scenic ASC Greenway in Fort Mill, South Carolina. This challenging yet rewarding event features a grueling 5K loop around and near picturesque Lake Haigler, providing participants with stunning natural surroundings throughout their journey. Registration for this limited-capacity race is highly recommended due to its popularity; securing your spot early ensures you won't miss out on the unique opportunity to run through one of Fort Mill's most beautiful green spaces. An aid station will be stationed at both the start and finish line, offering essential supplies such as water, snacks, and other necessities for endurance athletes. The race begins promptly at noon and concludes exactly twelve hours later at midnight, giving runners ample time to explore their limits on a well-marked course that winds through lush trails. All participants must complete their laps by the cutoff time of 12:00 AM; any unfinished loops will not be counted towards final standings. Bib pickup and check-in commence as early as 10:30 AM, allowing ample preparation before race day begins its intense pace. Post-race festivities are limited this year, with all runners, crew members, and spectators required to vacate the Greenway by 12:30 AM for safety reasons. For those unfamiliar with the area, detailed directions are available online or via a map link provided on the event website. It's crucial not to rely solely on GPS as it may direct you to an incorrect location—the entrance to Lake Haigler is located two miles north of Fort Mill along Highway 21 after taking Exit 85 from I-77 and turning left at the third light. With its combination of natural beauty, challenging terrain, and competitive spirit, the Lake Haigler 12-Hour Ultra Race promises an unforgettable experience for runners seeking a memorable endurance challenge.
Swag options are still being finalized but will be announced closer to the event date, ensuring participants can commemorate their achievement in style.
