Sorry, I meant an overall objective, a plan, rather than 'I am the best'. Knowing when to go, which stages are the important ones, even knowing where you can loose time. Knowing that you don't need to have the yellow jersey until the final stage. Biding your time and pacing yourself.
Voeckler, by his own admission, did not prepare as a GC rider would... because he didn't expect to find himself in that position! He's ridden balls-out every day in defence. In a sense, he's retained yellow because others have let him! THEY didn't see him as a long term threat either. They weren't expecting him to go the distance, so in a sense forgot about him. Think about the interviews with the GC guys and who they mention as the threats they see; it's not Thomas Voeckler. Or wasn't anyway! He's kind of been a fly in the ointment!
This tour has been excellent so far, best of the last few years that I've been watching. It's partly due to this maverick Voeckler. His approach is not your typical cagey GC rider's approach and it's worked for him thus far. Will tomorrow be a bridge to far? Can he produce the TT performance of his life? (My answers to those questions are 'no' and 'no'). Who knows, but I know I'll be watching!
