Run the Colfax Marathon:
This is your year to run the Marathon: 26.2 epic miles at 5280’ altitude – and zero attitude.
It’s the Ultimate Urban Tour of Denver. Start and finish in Denver’s City Park. Run through Broncos Stadium at Mile High – twice! Run through Denver Fire Station #1, along seven miles of rivers, lakes and bridges – including Sloan’s Lake. Race through eclectic neighborhoods, historic Lakewood, the bustle of Colfax Avenue, and downtown Denver – with views of the majestic Rocky Mountains!
26.2 miles at 5,280 feet elevation? This is one for the bucket list. The Colfax Marathon is a Boston Marathon qualifier race.

Colfax Double Marathon Challenge
It’s back for the 3rd year! We are issuing a challenge to all the marathon runners in the world … run a marathon race in early 2020 (between Jan 1-May 16, 2020) and then Denver’s Colfax Marathon! You get a sweet adidas duffle/backpack and bragging rights that you can run 26.2 anywhere including Denver at a mile high. More scoop here. Special consideration if you ran the Dallas Marathon – if you ran Dallas in December, 2019 we’ll count that as your “other marathon”.
