Sky put the brakes on fresh Froome
On a 148-kilometre route from Albertville to La Toussuire, which Wiggins had described as the toughest day of the route to Paris on July 22, the 32-year-old Londoner increased his advantage over Cadel Evans (BMC Racing) to three minutes 19 seconds.
The defending champion was overtaken in second place by Froome, who now sits 2:05 behind, with Vincenzo Nibali (Liquigas-Cannondale) third, 2:23 adrift.
