The toughest 100 miler east of the Rockies… Get ready to be tested !


The 160km race is actually an 80km loop covered twice. The 80km loop goes through sections of Mount Brome, Mount des Pins, Mount Gale and Mount Oak as well as dirt roads among the most bucolic country roads of the province. The trails are very varied: some are large and easy while others are single tracks and highly technical (rocks, roots, steep slopes and multiple turns).
