Join us on December 12, 2026, as we return to Forest Park for another exciting year of endurance running. This versatile event offers participants three options: one loop, two loops, or the full ten-loop challenge. The race begins at 8:30 AM and concludes after seven hours, giving runners ample time to tackle the scenic course. New this year is a relay option for teams of two, allowing each member to run five loops but ensuring no mid-loop swaps maintain the integrity of the distance covered by each runner.
Forest Park's lush trails wind through diverse terrain, offering both challenging ascents and serene descents amidst beautiful natural surroundings. Whether you're looking to test your limits with ten full laps or enjoy a more relaxed day out on one loop, there’s an option for every level of runner.
Participants will receive custom swag as part of their registration, with t-shirts set to be available again this year. Experience the camaraderie and excitement of runners pushing through the park's picturesque landscapes in what has become a beloved local tradition.
