Le Grizz Ultramarathon & Relay 2025

© © Le Grizz Ultramarathon & Relay

Short review

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 exact 2025 course is TBD, as construction on the North Fork Road over the past couple of years has caused course re-routes. Please check back in often, as will will update racers on the 2025 race course as soon as we are able!

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