Many think that the Steamboat Marathon and Half Marathon are the only times to race longer distances on road in Steamboat Springs....Not So, we have another one here for you! The Mountain Madness Half Marathon joins the Hayden Cog as one of the two oldest races in Steamboat Springs and the Running Series. This is a great race held over 4th of July weekend. This race takes runners along beautiful county roads with sweeping views of the Ski Area and the Yampa River.
