This year marks the 10th annual Colfax Marathon! As we’re not marathon runners, we’ll have to let Runner’s World tell you about this race: “If marathons on highways bore you, try this Denver race. Between miles three and four, the course passes through a fire station, where firefighters and police officers cheer runners. A few miles later, you’ll enter Mile High Stadium, home of the Denver Broncos, where you’ll run along the perimeter of the field and see yourself on the JumboTron.” (10 Editor-Approved Marathons for 2015)
