Trail du Mont Adstock

Trail du Mont Adstock and the Perseids edition of the Backyard Ultra-Vertical take place in Adstock, QC, on Saturday August 15, 2025. The event combines trail races, sprints on the Coulée track, and a Backyard Ultra-Vertical format that also runs at night under the Perseids.

Course maps and technical details are provided by the organizer. Location: 120 Rte du Mont Adstock, Adstock, QC G0N 1S0. ITRA points: 3; mountain points: 4.
