The Underground Circus 100
The Underground Circus 100 is scheduled for May 29, 2027 in Smyrna, Georgia, hosted along the Silver Comet Trail near 4625 Camp Highland Rd SE. The event offers multiple timed and fixed-distance options and operates on an honor system with race staff oversight.
Distances available:
- 100 Miles
- 50 Miles
- 24 Hours
- 12 Hours
- 6 Hours
The course is a five-mile out, five-mile in mix of trail and pavement configured as a straight out-and-back route. Runners may choose to run on the trail sidelines or on the asphalt. A race director leads runners onto the trail at the start of each outing.
There are two aid stations located at the start area and at the halfway point; both supply basic hydration and fueling items. The organizer can accommodate dietary restrictions if advised in advance. Finishers of the 100 mile distance receive a customized brass buckle; finishers of 50 miles and shorter distances receive awards, and all participants receive race souvenirs.
There are no checkpoint cutoffs and laps count only when runners cross the start/finish line. The event credits every mile run, follows an honor system, and the race director has final authority on disqualifications and course violations. Vans, campers, and RVs are permitted but no electrical hookups are provided. Volunteers receive race credits and a full 12 hour volunteer shift earns free entry for the following year. There are no refunds; remaining proceeds are donated to local homeless communities. Transferring to a shorter distance within the same race year is allowed. Registration closes May 28 at 11:59 PM ET.
