About the Event

The Underground Circus 100

A no DNF race😊 at Silver Comet Trail. The Trail has sunsets and sunrises. The route is asphalt and grass.125 ft of elevation & 2 indoor bathroom and you have wooded private spaces for business BUT no tissues on the trail!!. Bathroom is 24 hrs and the one past mile 5 til 7pm. Publix closes at 10pm, Chipotle, cupcake shop, 24 hr gas station has indoor bathroom Burger King Jersey Mike subs plenty of restaurants. Support these business by buying a cup of coffee for indoor bathroom privileges but it IS NOT MANDATORY they’re helping us out. The race has NO TURNS, run A STRAIGHT 10 miles OUT (one street crossing) then RUN or WALK 10 miles back. There is a timing mat and volunteers to help assure you’re running the full distance plus you’ll get signed in each loop and YOU can USE your gps WATCH to show your distance BUT the mileage must show how long each mile was. NO 4 minute mile lol!! Again flat asphalt and sidewalks which is surrounded by grass. The trails are beautiful:The trail will be open to the public but there is always someone at the aid stations.The race has a small town feel to it as I am around the course all day until the last runner is finished. The start of the race is close to the airport, it’s 20 minutes and the hotels are everywhere even as close as 6 minutes to the start. You can park overnight in the parking lot and or at the 24 hr gas station or shop parking lots. There are no electric outlets for campers or RV.This race is perfect for a 1st time Ultrarunner whom may not be used to staying up all day and night as my bike and volunteers will always be around to assist.Your MAIN assistance is at the START line is a fully stocked (aid station) will be supplied with cups, sports drink as well as various snacks hot foods anytime of the day, there is noodles, Mac n cheese, vegetables & potatoes, peanut butter and jelly and basically anything else that I can think of. I would encourage you to bring your go to items especially for the overnight runners. If you have a restricted diet bring your items for the race. I love you guys but please come prepared.The RD is on hand the entire time checking in on you. The RD has the final say on DQ. Please DO NOT CUT THE COURSE!! If you do not cross the timing mat your lap isn't counted. There are many walkers/runners throughout the day but the night you must have a headlamp or some form of reflective gear for your safety. The only wildlife is deers and possibly a grass snake but again some of the route is trail so remember we’re in their space not the other way around. Please please please DO NOT LITTER!! If you’re caught littering you’ll be forever banned because I had to almost cancel/move my race from one site of 5 years due to littering by runners. So please just keep it with you until you get to our trash cans. I will be all over the course checking on you to see if you need anything. Saturdays are busy in Atlanta especially when it's hot and it's usually 80-95 degrees during July so sunscreen 😉 and HYDRATION is extremely important. There are no sharp turns or non marked trails so no chance of getting lost. YOU RUN a straight line cross over a few bridges and just have fun; the only job will be run as much as you want. Remember don't stress about not making cut offs because we can always drop/change you to the timed events if you miss a cut offs. This is a challenge but definitely NO STRESS and the RD and volunteers are definitely here to help you. Pacers can sign up for the 6/12 hr depending on how long they’re running with you. For example if my pacer or pacers are/ is running 6 hours, then please SUPPORT the race and pay for 6 hours and yes you get credit for whatever miles you run during that time. If you have several pacers running 12 hours or more please sign up for 12 hours atleast. I want to see you finish ❤️. ALL proceeds go to helping the homeless. Please donate by bringing socks, underwear toothpaste toothbrushes please and thank you.
