Run the loop. Face the test. Draw your fate.
The Ozark Diamond Gauntlet is a brand-new endurance event held at Ballparks National in Lake of the Ozarks. This unique race blends timed-loop running with short, gritty obstacles and a mystery challenge at the end of every lap.
But for runners who want a classic endurance effort without obstacles, we also offer a Pure Running Division — a traditional timed run with zero challenges, zero tricks, and nothing between you and the miles.
You’ll run a 3.1-mile loop as many times as you can within your chosen time block. Each lap features 1–2 physical or skill challenges, and at the finish you’ll draw a numbered token that determines a surprise obstacle before you start the next loop.
As daylight fades, the final 3 hours of the 12 hours transform into the Night Gauntlet—a stadium-lit atmosphere designed for those who want next level!  Choose Your League
