15th Anniversary is in

Colfax Marathon rescheduled for October 16-17, 2021

We hope you are enjoying this great Colorado weather and getting in your fall miles!  Due to the impact of COVID, the Colfax Marathon is now scheduled October 16-17, 2021. More details on the weekend schedule (days and start times) will be forthcoming.  The Colfax Marathon will return to its historical May dates in 2022.

How it works:

  • If earlier this year you chose to defer to 2021, you are entered for 2021! You will need to confirm your registration details in early 2021. If your plans have changed, you will be able to choose to defer to 2022 at that time. More information will come in early 2021.
  • Registration will open early 2021 for new registrants.

Oct 16-17, 2021 Race Weekend details will be finalized after the Broncos schedule is announced in April. (For example, a Sunday home game may mean the main race day will be on Saturday, not Sunday. The 5K would then change to Sunday)
