This is an exclusive and professionally timed run, the only one along the shores of Flathead Lake! Featuring our popular 5k, in addition to a 10k and kid’s 1-mile run!
Our mission for this event is to not only create a fun family-friendly event for our community, but ultimately to create awareness around protecting and preserving Flathead Lake. This year, we’ve teamed up with not one, but two incredible local non-profits with like-minded missions. We are happy to announce a portion of proceeds will be donated to the Flathead Lake Bio Station and the Flathead Lakers. Both of these organizations focus on research, stewardship, education and outreach as a means to provide a voice and advocacy for our spectacular lake.
With our communities growing all around us, the use of Flathead Lake naturally increases, and our goal is to create increased awareness about the importance of continued lake health so future generations can continue to enjoy. Flathead Lake is paramount not only to the many forms of life it serves, but to the success of the small communities surrounding it.
Proceeds from this event ensure that not only the awareness continues to grow, but that the visitors it attracts stay for a night or two, buy coffee, beer and goods from our local, family-owned and operated businesses.
The 5k and 10k are open to all ages and families (strollers welcome), and the kids 1-mile run is limited to 12 and under. Join us in Volunteer Park on Sunday, July 27, 2025! Your contribution directly supports Flathead Lake and our beautiful community to ensure it may be enjoyed for generations to come.
This event will be held on Sunday, July 27, 2025 at Volunteer Park. All registrants will be given a Flathead Lake t-shirt; select your size when you register at FlatheadLakeRun.com. To guarantee your size, please signup prior to July 11th.
