St. Vrain for the Brain 5K Niwot, CO   Aug 8, 2026

The St. Vrain for the Brain 5K is a fun 5k in which all of the proceeds benefit the National Brain Tumor Society, an organization fighting to end brain cancer everywhere. The race takes place on the beautiful trails around Niwot and finishes up with fun activities on the field of Niwot High School.

Join for a morning of fresh air, community, prizes, and more. We invite all to participate, whether that be by running, walking, or skipping. Feel free to wear a costume, the best one gets a prize! 

This race was inspired by the amazing Meg Boyer. Meg showed people how to lead with strength, live with love, and fight with bravery, and her diagnosis of brain cancer in 2018 only emphasized all of those amazing qualities. Although we miss her dearly, we can still feel her presence by doing the things that she loved, namely running, enjoying the outdoors, bonding with friends and family, and fighting for a cure. By keeping Meg’s spirit alive and funding research for a cure to brain cancer, hopefully we can all be Brave Like Meg.
