Colfax Marathon - Run with Team CF

Team CF 2021 events

Run with Team CF at the Colfax Marathon!

When you register for any of the races at the Kaiser Permanente Colfax Marathon, you can choose the Cystic Fibrosis Foundation as your nonprofit of choice to show your support of our mission. Distances for this race include: full marathon, half marathon, Urban 10-miler, Marathon relay (5 people) or the Saturday 5k.

This is an opportunity for those with a passion for running to raise awareness and funds to help end cystic fibrosis, a life-threatening genetic disease that affects the lungs and digestive systems.

Fundraising is not required, but if you'd like to fundraise for the CF Foundation, please sign up on this page.

Please note that Run CF participants must register for the Colfax Marathon at www.runcolfax.org and registration fees do not go to the CF Foundation. Registration is through an external third party website managed by Timberline Timing Systems, and the registration fee will be processed through the www.simpleracereg2.com website. Timberline Timing Systems' privacy information is available.

Questions? Please contact Molly Smith at mmsmith@cff.org
