Backyard Ultra de Châteauguay - 24 heures (2025)

Event Overview

The event lasts for 1 full day, with runners departing every hour on a 6.7 km loop. Each runner must complete the loop within 60 minutes until only one runner remains on the course, or until the 24-hour period is complete. Runners who fail to finish a loop will receive a DNF (Did Not Finish) designation.

The concept of this event is inspired by the Tennessee Big Backyard Ultra.
