Backyard Ultra Châteauguay

Backyard Ultra Châteauguay is a 24-hour endurance race held at the Centre écologique Fernand-Seguin in Châteauguay, Québec. Participants run a 6.7 km loop, which must be completed within 60 minutes. After each loop, runners immediately begin the next. The race concludes when only one runner remains or after 24 hours. The course is contained within the ecological centre, focusing the challenge on repeating the loop as fatigue sets in. This is the event's second edition, which saw 74 participants. Proceeds benefit Héritage Saint-Bernard, funding local conservation efforts for the region's natural environments.
