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 in early 2018 (between Jan 1-May 19, 2018) and then Denver’s Colfax Marathon! You get a sweet adidas duffle/backpack (check out the pic below!), and bragging rights that you can run 26.2 anywhere including Denver at a mile high.    Special consideration if you ran the Dallas Marathon – if you ran Dallas on December 10, 2017 we’ll count that as your “other marathon”.  

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

Prior to our Expo weekend, please go to this link and and verify you completed another marathon by attached the URL of those results.  Then your adidas Colfax gift will be waiting for you at the Expo at Mile High Stadium!


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 2017 double marathon challenge gift at the Expo.    The 2018 gift will be a Colfax adidas backpack/duffle.   Pic to come!
