The Underground Circus 100

The Underground Circus 100 is a unique ultramarathon event taking place on Atlanta's scenic Silver Comet Trail, featuring distances of 100 miles, 50 miles, and a 24-hour challenge. The course is relatively flat and fast, offering both asphalt and grass trail options, making it ideal for first-time ultrarunners. Participants can enjoy a supportive atmosphere with aid stations stocked with snacks and drinks, and the race emphasizes a no DNF (Did Not Finish) policy.

All proceeds benefit the homeless, encouraging donations of essential items. The event fosters a community spirit, with volunteers and race directors available to assist runners throughout the race. Visit the organization's website for the most recent information.
