Marathon races near Johns Creek

The Silver Comet Half & Full Marathon takes place entirely on the Silver Comet Trail in Mableton, Georgia, located just outside Atlanta, on the final Saturday of October. The primary races are USATF-certified out-and-back courses, and a 10K is also included in the race series. The marathon is eligible as a Boston Qualifier, and the level, paved trail offers both new runners and those seeking personal bests a straightforward, quick path free from city traffic. The course crosses extended sections of paved path through forested areas in Atlanta’s northwestern suburbs. It utilizes the Silver Comet Trail in Cobb County, which is part of a former rail corridor beginning just inside the perimeter highway and extending west toward Alabama. Typically, over 1,500 runners participate, and the trail also attracts cyclists, families, and casual users on days other than the race. Silver Comet Races organizes the events; the organization was established by Dana Greene, and funds raised from the race benefit community initiatives and school running clubs.

The Amicalola Falls Marathon takes runners directly into Amicalola Falls State Park in Dawsonville, Georgia, with the 729-foot waterfall serving as the race’s focal point. This December trail event offers both marathon and half marathon distances. The full marathon consists of two 13.1-mile loops. The course is primarily singletrack, with some gravel or paved sections, and the full marathon includes approximately 3,200 feet of elevation gain. The course winds through forest paths, along creeks, and past overlooks surrounding Amicalola Falls, Georgia’s tallest cascading waterfall. Each marathon loop features the 605 steps of the Appalachian Approach Trail, which full-marathon participants ascend twice near the falls. The route is marked with flags and signs, aid stations offer provisions and medical assistance, and the race has a 7-hour time limit. Participants receive a medal and athletic shirt, with special awards for top finishers in overall, masters, and age categories; no prize money is awarded.
