While the goal is to keep running as long as possible, it offers an exciting and unconventional challenge for those who enjoy pushing their limits. The event draws ultra-marathoners and adventurers alike, testing not just physical endurance but also mental toughness. Set in the vibrant city of Austin, this marathon combines the thrill of competition with the unique camaraderie of the backyard ultra style, offering a race unlike any other.
