Prepare for an extraordinary ultrarunning adventure at The Underground Circus 100, set for July 4, 2026, in Kennesaw, GA. This unique event, known for its "no DNF" philosophy, offers a welcoming atmosphere for both seasoned ultrarunners and those tackling their first ultra. Participants can choose from a variety of distances, including 100M, 24HR, 50M, 12HR, and 6HR options, with the flexibility to adjust their distance during the race if needed.

The scenic course primarily navigates the beautiful Kennesaw Mountain Trail and sections of Atlanta's Silver Comet Trail, featuring a mixed terrain loop that includes relatively flat asphalt segments, grassy trails, gravel roads, and wooded sections with some rocks and roots, offering small inclines for variety. Runners will enjoy picturesque views, including historic battle sites and 18th-century homes, alongside stunning sunsets and sunrises for those pushing through the longer distances. Aid stations are fully stocked with sports drinks, various snacks, and even all-night soup and pizza, ensuring runners are well-supported. An indoor bathroom is conveniently located at a nearby Texaco station, and the race's "small town feel," coupled with an ever-present Race Director, creates a supportive environment where every runner is encouraged to finish.

Typical race day conditions in early July include highs around 90F and lows around 68F, with a 16% chance of precipitation, so runners should prepare for warm weather. Beyond the personal challenge, The Underground Circus 100 holds a deeper purpose: all proceeds benefit organizations assisting the homeless, with runners encouraged to bring donations like socks and toiletries. This makes The Underground Circus 100 more than just a race; it’s an experience that combines a friendly, flexible course with a meaningful cause.
