Group Training Runs

Welcome to our 2021 Group Training Runs!

If you are a store or club (or other) that would like to include one of your training runs as a recommended training run, email us at

Training can be way more fun together!  Various Colorado groups and businesses independently organize and sponsor group runs throughout the year.  These group runs are a great way to get ready for the Colfax Marathon races.  While the Colfax Marathon does not plan, organize or sanction the group runs listed below, members from our Colfax Ambassador Team attend these group runs to join in the fun.  Our Ambassadors love running, talking running, have cool running items to give away, and can answer your race questions.
