DH and I both kind of anticipated this. Our theory was that Landis is no idiot...he knew yesterday was not in the cards for him and that today's stage was more difficult. We both think that once he realized that the day was 'off' for him, he just backed off to conserve as much as possible both for today's stage and for the TT.
I'm so excited to see that he did well today! I can't wait to go home and see it for myself!! :D
