The CSM is a two day 160km ski marathon, the longest in North America. It's a test of endurance and skill with successful completion meaning entry in the coveted ranks of the Coureurs des Bois. Filming it meant hours spent in the freeezing temperatures of a Canadian winter waiting for the skiers to pass by. In this film we join Richard Webster as he trains for the event and then embarks on the marathon itself. Will he make it?
