Boréalys Mont-Tremblant by UTMB invites you…

…to tread the relentless trails of Quebec’s folklore and face the trembling mountain.
More than just an ultra-trail, Boréalys Mont-Tremblant by UTMB is a journey between darkness and light — from the shadow of deep forests to the uplifting return beneath the village steeple of Tremblant.

Runners make a pact with the spirits to earn the right to set foot on the trembling mountain and reach the Devil’s River, a mythical source said to offer precious stones.

Boréalys Mont-Tremblant by UTMB welcomes you into a world where culture and nature come together to deliver an extraordinary athletic challenge.

With its six rugged courses, Boréalys Mont-Tremblant by UTMB is a true adventure of endurance and self-discovery in the heart of Quebec’s wild nature.

Every step counts toward advancing our understanding of epilepsy and breaking down the stigma that surrounds it.
