Thank you to our 2024 Volunteers!


Be A Volunteer

We pride ourselves on the success of the Denver Colfax Marathon, which could not be possible without the support of our amazing volunteers!  Colfax Marathon offers an awesome opportunity to get involved on race day without actually running but by becoming a vital part of our race crew in supporting athletes from the start line all the way through to the beer garden and every step in between.

Will you join us for a fun weekend in City Park and become part of our essential race crew?  Is that a YES?  Then you are in the right place!  All volunteer positions are now open, and we have a job that will suit you!
