Usually, yes. When Lemond won on the final TT, it was the last day.
But I think if today ends with Sastre, Evans and/or others within a few seconds of each other, we could see a contested last stage. Hasn’t happened in a while.
Fabian Cancellara, the current World Champion (he gets to wear a jersey with pretty rainbow sleeves...) has set the standard to beat. Now 1:04:12 - a full 1:16 ahead of David Millar.
