7 Bridges Marathon is a long-distance running event that kicks off at Coolidge Park in Chattanooga, Tennessee. The course crosses the bridges downtown, so runners get a scenic tour of the Scenic City on foot. Coolidge Park is a riverside green space with its famous antique carousel and a view of the Tennessee River. Whether you're chasing a personal best or cheering from the sidelines, this is a great morning out. Lace up, bring your crew and soak in the energy of race day.
