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.

The Backyard Ultra-Vertical requires completing one loop each hour until only one runner remains. The maximum duration is 24 hours; the winner is determined by the fastest lap within that framework.

The course features a climb of 250 m over 1.2 km on the Coulée track. Day and night sprints are offered on that track. Several trail events run in parallel to provide different distances and formats.

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.
