About This Race
The 26.6K at Boréalys Mont-Tremblant occupies strategic ground in the event's distance lineup. Long enough to demand respect and preparation, yet short enough to remain within reach for runners stepping up from road half marathons or testing their readiness for longer mountain efforts. The course delivers a genuine Laurentian experience through the forests and ridges of Mont-Tremblant, where technical footing and extended climbing separate this from flatland racing. This distance draws a mixed field: experienced trail runners treating it as a hard tempo effort, ultra-curious road runners making their mountain debut, and local Québécois athletes who know these trails intimately. The route shares segments with the longer Boréalys distances, benefiting from the same well-marked course and UTMB-standard aid stations. Finishing times typically range from under three hours for strong mountain runners to five-plus hours for those taking a more measured approach. As part of the UTMB World Series, the race attracts an international field while maintaining its distinctly Québécois character. French and English blend at the start line, and the mountain's name—"trembling mountain" in Algonquin—hints at the glacial history beneath your feet. Mont-Tremblant village provides the base, where cobblestone streets and resort infrastructure meet serious mountain terrain just minutes away.
The route explores Mont-Tremblant's trail network through mixed hardwood and conifer forest, with sections of exposed ridge and technical singletrack. Runners encounter the mountain's signature features: root-laced descents that demand focus, granite outcrops, and forest trails that shift from smooth to demanding within meters. The course includes fire road connectors between technical sections, offering brief windows for rhythm and recovery before the next challenging stretch.
