His goal should be, first and formost, to ride into Paris (on his bike!), finishing the 3 weeks. It will be a test of his mental toughness to for the first time, go into the Tour unable to compete with his gc rivals. I don't see him having the form to do that and how he responds to that scenario will determine what his ultimate Tour outcome will be. He's been saying that he's not being overly ambitious in terms of his anticipated performance so I'm going to give him the benefit of the doubt and say that he's matured through this period of adversity, developed a degree of mental toughness that may have been missing/or lost before and that will carry him to Paris. A top 30 finish in the gc with a valiant but unsuccessful attempt at a stage win.
