Why is/was Armstrong ahead of Contador? (no spoilers)
After 4 stages, Armstrong was or is 19 seconds ahead of his teammate Contador. Obviously this is because he did a very good initial time trial to stay within striking distance, and then in stage 3 he was in the front part of the peloton when it split, and Contador was caught in the back part.
So how did Armstrong pull off that stage 3 coup:
Just lucky?
Stronger riding?
Better strategy?
Teammates favour him over Contador?
Team Director ordered it for strategic/advertising purposes?
