Colfax Marathon

Each year thousands of runners and supporters come to our City Park to kick off their challenges and participate in Denver’s only marathon.  The Colfax Marathon celebrated its 20th Year in 2026 and the events are more popular than ever. City Park provides the perfect spot to check in and send off the runners on their miles ahead.  Learn more at their main website. Registration for 2027 is just around the corner.
