The Underground Circus 100

Smyrna, United States • 25 May 2024

The Underground Circus 100 is a unique trail run held on Atlanta's Silver Comet Trail, offering distances of 100 miles, 50 miles, 24 hours, and 12 hours. The race is known for its scenic route, small-town feel, and well-stocked aid stations. Participants can enjoy a relatively flat asphalt trail surrounded by beautiful wooded areas. The event is perfect for first-time ultrarunners and those looking for a fast time, with no chance of a Did Not Finish (DNF). All proceeds from the event go towards helping the homeless, and volunteers are appreciated with race swag and free entry to next year's event.
