About This Race
The 80.7K course at Boréalys Mont-Tremblant by UTMB takes runners deep into the Laurentian Mountains of Quebec, where dense forests and technical singletrack demand sustained focus and mountain running competence. Part of the UTMB World Series, this distance serves as a serious ultra introduction to Mont-Tremblant's terrain, typically requiring 8-12 hours to complete. The race draws its name from the region's namesake peak—Mont-Tremblant, or "trembling mountain"—a nod to the Algonquin legends that echo through these ancient woodlands. Runners encounter the full character of Quebec's trail network: rooted climbs, rocky descents, and stretches where navigation skills matter as much as fitness. This is mountain running in the Eastern Canadian style, where humidity and elevation combine to test runners differently than the high alpine. For those seeking UTMB qualifying points or looking to step up from marathon distance, the 80.7K offers a legitimate proving ground. The race infrastructure benefits from UTMB's organizational standards while maintaining the distinct flavor of trail running in La Belle Province.
The course winds through Mont-Tremblant's trail systems, combining singletrack through hardwood and coniferous forests with technical sections that require careful footwork. Runners should expect rooted trails, rocky passages, and sustained climbing, though specific elevation gain data is not currently published. The August timing means full vegetation and potentially warm, humid conditions that add to the challenge.
Aid stations follow UTMB standards, positioned at strategic intervals throughout the course. Night running is likely for mid-to-back-of-pack runners, making headlamp preparation essential.
