The Underground Circus 100 offers a unique no-DNF experience on the picturesque Silver Comet Trail. This out-and-back course spans 10 miles, extending 5.0 miles to a bike shop and then returning on a relatively flat asphalt pathway, bordered by a grass trail for a comfortable run. The trail showcases beautiful wooded areas, providing a scenic backdrop as you navigate the route. Although it’s open to the public, aid stations are staffed throughout the race, ensuring runners have support. The event embodies a community spirit, with the race director present to assist every participant until the last runner crosses the finish line. Conveniently located in Smyrna, just outside Atlanta, the race is close to various amenities including restaurants and hotels, as well as historic attractions like the MLK Jr. house and the Civil Rights Museum. Ideal for first-time ultrarunners, the race allows participants to enjoy the challenge without the stress of strict cutoffs, with the option to switch to timed events if necessary. Runners should be prepared for potential overnight conditions and varying temperatures. With no sharp turns or unmarked trails, this race ensures you can focus solely on running, while supporting a good cause by bringing donations to help the homeless.
