Now in its 18th year, the Colfax Marathon Partnership is a nonprofit 501c3 with the mission of producing the premier marathon weekend in the Mountain West Region, committed to community, philanthropy, and fun. Originally created by the cities of Denver, Lakewood, and Aurora to recognize Colfax Avenue, the longest main street in America; it’s Denver’s only marathon. The race has grown to be a nationally recognized event featuring unique courses incorporating the iconic landmarks of the Mile-High City. In addition to Marathon Weekend, there are other events in the year such as the annual Colorado Running Hall of Fame evening with new inductees and high school athlete recognition. And, there are other races during the year – which include Runner’s Reunion, Mile High Women’s 5K, and Welcome Back Denver 5K.
