please join us for our 15th year anniversary

The tremendous success of the Colfax Marathon is made possible because of you.  We appreciate the support you give runners as they run for their health, to reach a personal goal, and in many cases to support a charity.


Click HERE to register as a individual volunteer.  Your family and friends can register for the same time slot if you’d like to work together.


For information on earning funds as a group, please contact Carol Hiller: carol@runcolfax.org

Nonprofit groups that volunteer can earn money for their nonprofit.   Opportunities include:

  • Indoor – at our Expo at Empower Field at Mile High on Thursday October 14th and Friday October 15th
  • Outdoor – at City Park and on the race course on Saturday October 16th.
  • Water station opportunities have opened up for 2021 (Saturday, October 16th) !   These are normally taken up, so this year is your chance to volunteer this year and have first dibs for 2022!

We are thrilled to announce Johns Manville as the sponsor of the Colfax Marathon Volunteer Program!
