Race Info
The Silver Comet Marathon runs on the paved Silver Comet Trail, a former railroad corridor west of Atlanta in Mableton, Georgia. The out-and-back course starts near the trail's Floyd Road trailhead, heads southwest toward the Alabama state line, then finishes near the Mavell Road trailhead in Smyrna. It is USATF-certified and a Boston Marathon qualifier, marketed as flat and fast. The race has run annually for over a decade alongside a half marathon on the same morning, part of the Silver Comet Races series that also puts on a spring 10K.
