I prefer to take the PBP route between Fougeres and Versailles
More seriously, it doesn't look like a route for Wiggins to win; I reckon he'll have a much better chance at the Giro. Then again, it would look bad for the winner not to defend his crown. My prediction:
1) Sky say that Wiggins is going for both.
2) Wiggins does go for the Giro.
3) Wiggins and Froome are announced as co-leaders for the Tour.
4) Froome comes to the front after the first week, at which point he's announced as leader on the road, which is actually what they'd planned all along.
