Colfax Makes Top 10 in 2015 & 2016 in Runner's World
Runner’s World selected Colfax as 1 of 10 “Marathons to run” in 2015, and just announced Colfax as 1 of 10 “Great marathons for first timers” for 2016.
“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.”Read More >
