  Join us for our 8th year of our point-to-point mountain marathon show casing the newest trails on the Foy's to Blacktail Trail system! Maximum 100 sign ups allowed, so sign up soon! Racers with gather at Herron Park at 5:30 a.m., with final bib assignment and a pre-race meeting starting promptly at 5:45. Busses leave promptly at 6 a.m. to take racers to the start at the Lakeside to Blacktail Trail (NO parking at the start of the race). More details about the course (see cool interactive map from OnX Backcountry), drop bags, Race Series, etc., can be found on the main website, Foy's to Blacktail Trail Marathon.

  All runners will be eligible for a random give away of cool swag like a pair of running shoes!!

  Remember to bring your bear spray. All racers must race with it because there is a real risk of running into wildlife such as bears and/or mountain lions that feel threatened and get aggressive. Even those at the back of the pack need to be aware of startling any of these charismatic megafauna.

  There will be a strict 12 pm cut off time to reach the Emmons Saddle aid station, however even the slowest runners in the past have made it under this cut off. You will need to be moving at an average pace of >3 mph to meet this cut off.

  This race, along with the FTBT-Herron Half Marathon, 10k, & 5k trail races, are our longest-running annual fundraisers. The money raised from the races goes directly to building and maintaining trails in the 40+ mile FTBT system, including new trails on Emmons Ridge south to Blacktail Mountain. In addition to event fees, our trails thrive largely in part to our dedicated sponsors. See the main webpage for a list of current and past sponsors. If you are interested in sponsoring this year's or future races, please reach out to [email protected].

  The Flathead Race Series!

  See main website for details. Races include FTBT races, the Big Mountain Run, the Whitefish Trail Blazer races, and the Le Grizz races. At the end of the year, Competitive Timing will compile a list of all who have completed the series as well as a leader board.

  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 two outstanding local nonprofits—the Flathead Lake Biological Station and the Flathead Lakers. A portion of all proceeds supports their ongoing work in research, education, stewardship, 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 12 and under. We’ll gather at Volunteer Park on Sunday, July 26, 2026, to celebrate community, movement, and conservation. Every registration helps support Flathead Lake so it can be enjoyed for generations to come.

  The event takes place on Sunday, July 26, 2026, at Volunteer Park. 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 your preferred shirt size, please sign up by July 6, 2026.

  Le Grizz is a 50-mile Ultramarathon run just to the west of Montana's Glacier National Park on a gravel road that parallels the North Fork of the Flathead River. Runners will find themselves gaining views of the magnificent Crown of the Continent, made up of Northern Rockies of Southern British Columbia and Glacier Park, and surrounded by the changing colors of the aspen and larch.

  The 2026 course is an out-and-back route which will begin and end at the Glacier Institute's Big Creek Outdoor Education Center, following the North Fork Road just beyond Red Meadow Creek, with a brief detour into our Polebridge Mercantile aid station.

  The course contains approximately 2,300 feet of elevation gain across the 50 miles – metrics that are true to the traditional elevation profile of Le Grizz from the legacy Spotted Bear course. The road is undulating gravel with occasional gentle inclines – excellent for folks seeking their first ultramarathon finish.
