Colfax Run 2020

In an effort to branch outside of the animal rescue community, we will be celebrating our 7th year as a charity team at the Colfax Marathon races. Join us as your charity partner on Saturday MAY 16, 2020 in DENVER, CO, for the dog and stroller friendly 5k. Then on Sunday MAY 17, join us for the Urban 10, Half Marathon, Marathon, and Marathon Relay! The Colfax Marathon races are Denver's largest running event in the Rocky Mountains and it partners with over 200 nonprofits. It is the second largest race in the U.S., only behind the New York City Marathon, and we are beyond honored to be a part of it all, and hope you will join us!

When you register, be sure to select No Kill Colorado as the charity you are supporting!  

When you run in any of the races over the weekend, NKC's logo will automatically be added to your race bib to show off that you are running for a non-profit organization dedicated to saving the lives of every healthy and treatable homeless pet in Colorado! Sign up by March 14 to be the price increase!

We are designing a shirt for anyone that signs up and starts a No Kill Colorado fundraiser with us. Go to Mighty Cause and start your Fundraiser for No Kill Colorado now. You can do it even if you are not running! If you sign up by the April 1, 2020 deadline, you can request a tech shirt for the races!
