160 km

of trail running

Fall deconfinement BONUS !

And so you get to register, reserve in essence, your spot on the starting line, for zero money down, zero cancellation and no obligation until August 10th, date at which we will decide whether we will hold the event or not. Obviously, the government might have made that decision for us beforehand, in which case, you will learn our fate at the same time as us.

In the meantime, let hope guide you and register. Do it sooner, rather than later as we will have limited spots available. Given the situation, the government might limit us even further. In that case, we will go wiith the traditional 1st come, 1st serve basis.

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


The 160km trail 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).
