Km 166.0 - Port de Balès - 19.3 km climb to 6.1 % - Category HC

Left by the wayside?
It is a sure thing that some riders will lose Le Tour because they are not sufficiently skilled at descending. From the Port de Balès to Bagnères-de-Luchon, the bends are extremely delicate. Whats more, the foot of the Peyresourde slopes are only three kilometres from the finishing line, meaning there is no way of clawing back any ground lost. To date, the Port de Balès has only been climbed once by Le Tour, in 2007. Beforehand, there was not even any tarmac. It was specially laid for cycling races. This pass is magnificent, hard and not very wide. Once the riders reach the top, a good downhill rider can open up the gaps, for example Samuel Sánchez, because it really is a very technical descent. More importantly, there may well be a lot of riders left by the wayside.

As Billy Fish would say, 'big damn hill!'.
If Astana does a similar thing tomorrow we could only have a breakaway and AC and AS after the 2nd 2nd category climb.
I can’t see AS and AC on the same team. For one it would be depressing as a fan, one of the two best in the business would have to work for the other.
