Canadian Ski Marathon

This looks like a unique and fun event.  A 160km ski over 2 days between Lachute and Gatineau winding through the picturesque eastern Laurentians.  Almost the equivalent of skiing a Vasaloppet  two days in a row!  There is an overnight stop in Montebello.  It is billed as North America's oldest and longest Nordic ski tour.  You can ski sections, the whole thing or even carry your own gear and camp out overnight.  Always scheduled for the second weekend in February each year.
