From the Organizer
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.

About This Sport
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
Running
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
