The Denver Colfax Marathon is the premier marathon weekend in the Mountain West Region, committed to community, philanthropy, and fun. This year is the 20th anniversary of the race, so extra special! 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.

Parkinson’s Champions are racing toward a cure! Our Parkinson’s Champions athletes raise funds and awareness for the Parkinson’s Foundation while competing in some of the world’s most popular endurance events. Every step we take brings us closer to a future without Parkinson’s disease, because Parkinson’s isn’t a sprint, it’s a marathon. Learn more at ParkinsonsChampions.org.
