Great read here from Chris Riley on his club’s website

During my attempts in 08 and 09, I began to stretch my abilities on the descent to frightening new levels. Short sections of complete lack of control were buoyed in my faith that speed would carry the body of the rider across even the worst of terrain. And to some degree it worked beautifully with a new understanding of how the really fast descenders are able to seemingly float across even the most impassable of terrain.
