The Wolfpack Ultra Championship

Hamilton, Canada • 20 Sep 2025

The Wolfpack Ultra Championship takes place in Hamilton, Ontario, showcasing Conservation Halton’s rugged backcountry. The event centers on two 50K formats: a solo 50K Ultra and a 50K Team Relay (five runners of 10K each). Runners navigate technical climbs, winding forest trails and open ridges, with sweeping autumn views and a strong sense of community.

The race emphasizes endurance, teamwork and an unforgettable outdoor experience, supported by STAC volunteers and marshals.
