  Well, our friend Chris Brewer at www.Paceline.com answered the question that was in my mind today and that is: how long does it take the peleton to reel in a breakaway? Then answer is, the peleton can make up 10 km for every minute of the break. So, if the breakaway is 10 minutes ahead of the main pack, they would have to start the pursuit of the break before the 100 km-to-go point. Had there been anyone in the break today that the Posties were worried about, they would have had to spend 2/3's of the stage chasing the break. Fortunately, there was no one that threatens Lance with their climbing ability, so the break held. So, there you go, learned something about tactics today.
