About the Event

Run (or walk!) for the love of Flathead Lake!

Join us for a scenic, professionally timed race that hugs the beautiful shoreline of Flathead Lake. Participants can choose from a 5K, a 10K, or a kid-friendly 1-mile run—making this an event the whole family can enjoy.

At its core, this race is about more than miles and medals. Our goal is to bring the community together for a fun, family-forward experience while shining a light on the importance of protecting and preserving Flathead Lake. Once again, we’re proud to partner with the Flathead Lake Biological Station where a portion of all proceeds supports their ongoing work in research, education, and advocacy for the long-term health of the lake.

The 5K and 10K are open to all ages, with strollers welcome, and the kids’ 1-mile run is reserved for participants ages 10 and under. We’ll gather at Volunteer Park on Sunday, July 25, 2027 to celebrate community, movement, and conservation. Every registration helps support Flathead Lake so it can be enjoyed for generations to come.

All registered participants will receive an official Flathead Lake Run t-shirt—be sure to select your size when registering at FlatheadLakeRun.com. To guarantee a shirt, please sign up by July 5, 2027.
