The ultra where forest, devil, and spirits come together

About the race

Boréalys Mont-Tremblant by UTMB invites you to dive into the legends of Quebec folklore and take on the trails of Montagne Tremblante.

More than just an ultra-trail, Boréalys Mont-Tremblant by UTMB is a true journey between darkness and light, from the depths of the forest to the redemptive return to Tremblant's village steeple.

Runners seal a pact with the spirits for the right to tread the trembling mountain and thus reach the Devil’s River, said to by a source of precious stones.

Boréalys Mont-Tremblant by UTMB invites you into a universe where culture and nature unite to offer an extraordinary sporting challenge.
