Colfax Double Marathon Challenge

Running a marathon, 26.2 miles, anywhere in the world is an amazing accomplishment!  It takes months of training, sacrifice, and personal battles just getting to the start line.

We are issuing a challenge to all the marathon runners in the world … run a marathon race between Jan 1, 2020  and May 15, 2021 and Denver’s Colfax Marathon!  You’ll get an awesome gift – last year was a sweet adidas duffle, and bragging rights that you can run 26.2 anywhere including Denver at a mile high.  Please note:  Races must be timed and in-person, and results must be online.  Virtual races are not eligible.

We’ll have plenty of fun group runs around town to get ready for your big day!


Now that's a gift!

Run 2 marathons – it’s worth it!  Check out this excited runner (and Colfax ambassador) when she picked up her double marathon challenge gift at the Expo – a cool adidas duffle.  This year’s gift will also be branded Colfax – announcing soon!
