Colfax Marathon

May 17 - 19, 2024

About the Colfax Marathon

The Colfax Marathon is Denver’s biggest race weekend! A weekend of food, fun, and a variety of races. There is a race for all levels of runners and walkers to choose from including the Marathon, Marathon Relay, Half Marathon, Urban 10 Miler, and a 5K.


The best part about Colfax Marathon is the race’s focus on nonprofit partnerships. That’s where Jeffco Human Services Foundation comes in! As a runner, you can choose to run for a charity partner. Running for JHSF, you can help fundraise to support JPP families working to overcome poverty. Not a fundraiser? Runners and sideline supporters can also make a personal donation to JHSF. Others become ambassadors for JHSF and help raise awareness about the important work JPP does and the impact it makes for families in our community. Signing up to run with Jeffco Human Services Foundation does not require you to do anything extra. We appreciate any and all support you may be able to give and we look forward to cheering you on at the races!


How do I register to run for JPP families? 

  • Visit the registration page for the race you want to enter 

  • Look under “Additional Questions” 

  • Select “Yes” for the question “Are you considering raising funds or awareness for a charity?” 

  • A drop-down menu will appear for you to select Jeffco Human Services Foundation as your nonprofit partner!

Thank you for making this year's event a success!

This year, Jeffco Human Services Foundation raised $7,000 to support families in the Jeffco Prosperity Partners (JPP) program.  A special shout out to marathon runner extraordinaire, Mary Rueda, who has gone above and beyond to raise over $5,000 for the fundraiser! Mary is an avid runner and Jeffco employee who has been an incredible advocate for our mission. 

Thank you, NREL!

Jeffco Human Services Foundation recently attended the Colfax Marathon Award Celebration to honor the winning runners and relay teams. At the event, the National Renewable Energy Laboratory relay team presented the foundation with a $1,000 donation they won for placing third! 


We are incredibly grateful to Aaron, John, Kim, Brent, and Norwood for choosing to support our mission! Their kindness, compassion, and dedication are truly commendable and their contribution will support JPP families who are making great strides to achieve economic stability.
