Smooth Running 5K Endurance Challenge 2026

The Smooth Running 5K Endurance Challenge is a 12-hour lap event held on Saint Simons Island, Georgia, headquartered at 1612 Frederica Road. Participants may begin their race at any point between 7 AM and 7 PM, with the final lap requiring commencement by 6:30 PM. Each lap covers 5K. Completing at least one lap grants a medal and a shirt. Participants aiming for more can continue adding laps at their preferred pace throughout the 12-hour duration. The course consists of paved trails shaded by oak trees, with each lap concluding back at the start/finish area. This setup accommodates individuals seeking a leisurely few miles as well as those aiming to maximize their distance. An aid station provides water and snacks, though the event operates on a self-supporting basis. Jimmy John’s and Smoothie King are also located near the start/finish. Special medals and prizes are awarded to the top male and female finishers based on total miles completed.
