It isn't often that you will descend a route before you ever climb up the thing. However when I climbed the Lesuer route on the Dru a few years back, the easiest and safest descent is rappelling the Dru Couloir Direct. It was dark and whilst hanging in the air, due to it's steepness of the route, only the beam of my head torch would light up small sections of the route. I couldn't imagine how big your forearms would have to be to climb something this wild. Turns out not not big at all, cause Calum and I climbed it the other day!
