Denver Colfax Marathon

The Denver Colfax Marathon is Denver, Colorado's only marathon event, celebrated as the largest marathon weekend in the Rockies. It features multiple race distances including a full marathon, half marathon, urban 10 miler, and a marathon relay with divisions for corporate, government, public schools, and open teams. The marathon course is a Boston qualifier, passing through iconic landmarks such as Empower Field at Mile High and a fire station, finishing with a lively post-race party.

The half marathon includes a unique mile through the Denver Zoo. The urban 10 miler offers a shorter route through downtown and local highlights. The event promotes community, charity, and fun across two days of racing and festivities. Visit the organization's website for the most recent information.
