Group Training Runs

For the 2017 Colfax Marathon season, we hosted over 35 fun group training runs at running store, breweries, and restaurants from Castle Rock to Fort Collins! Our Ambassador Team had a blast talking and running with all of you!

We are ready to beat that number this year and have already begun putting together some fun training runs around town! See below and check back often!

If you are a store or club that would like to include one of your runs for the 2018 season, email us at
