About
Mark your calendars for September 19, 2026 – the Full Marathon is making an exhilarating comeback! Gear up for an epic run that could secure your spot in the next Boston Marathon. Immerse yourself in the beauty of a fully paved downhill course, with no tunnels or trails to slow you down – and no Boston Qualifier time penalties to worry about. The marathon route unfurls from the lofty Mud Mountain Dam through enchanting farmlands and forests, offering a stunning 1,200-foot drop to the finish line at the historic McMillin Bridge. And for those seeking a shorter challenge, the Half Marathon promises a scenic, gradual descent along the Foothills Rail Trail, also culminating in a remarkable finish at McMillin Bridge. There's simply no reason to miss out on doing the dam thing!
