Le Grizz 50-Mile Ultramarathon Details


This year's course will be back on the North Fork Road, beginning and ending at the Big Creek Outdoor Education Center (BCOEC). After the 7 am shotgun blast at the BCOEC, runners will head south for 6.5 miles only to turn around where the pavement – and civilization – begins. Runners will then head northbound for 25 miles, summiting Vance Hill before turning around once more to head back to BCOEC for their final 18.5 miles. See maps below for details, and/or click here to view the Strava route.

With approximately 2,300 feet of elevation gain across the 50 miles, this course is remains true to the traditional elevation profile of Le Grizz – undulating gravel roads with occasional gentle inclines – excellent for folks seeking their first ultramarathon finish.

While exact aid station locations are TBD (we're working on them now and will release the deets soon!), runners can plan on support being provided every 5 to 8 miles, while also stopping for aid at iconic landmarks like Home Ranch Bottoms and the Polebridge Mercantile.

Stay tuned for updates as they will be posted and emailed as soon as we are able!
