CINCINNATI'S LONGEST
RUNNING ULTRA
MARATHON
For over 20 years, we’ve been trail racing in historic Mt. Airy Forest, just a stone’s throw away from downtown Cincinnati. Mt. Airy Forest offers an unparalleled backdrop for endurance runners looking to challenge themselves and find solace in nature. Our ultra marathon races attract trailblazers of all levels, from seasoned veterans seeking their next big accomplishment to enthusiastic newcomers eager to test their limits.
Ultra marathons are not just races; they are a journey of self-discovery and determination. The camaraderie among runners, the thrill of traversing rugged terrains, and the sheer beauty of the forest make each race an unforgettable experience. With well-marked trails, fully stocked aid stations, and a supportive community of fellow runners and volunteers, you’ll feel both challenged and encouraged every step of the way.
