The Wolfpack Ultra Championship

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. Proceeds benefit STAC Hamilton youth programs, and participants can enjoy exclusive ultra-themed swag and sponsor perks. Aid stations provide Xact Nutrition and hydration to fuel the day’s challenge.
