Pinot took a solo win ahead of a rampaging Nairo Quintana (Movistar), who was attempting to make up his two and a half minute overall deficit on Froome.
Quintana attacked early on Alpe d’Huez, accelerating away from Froome and clawing back one minute and 20 seconds – but not enough to take the yellow jersey.
Although Froome and his Sky team-mates looked fatigued after three weeks of hard racing, they collectively put a limit on Quintana’s move. Barring unforeseen disaster on the 2015 Tour’s final stage into Paris on Sunday, Froome has secured his second Tour title – the first British rider to win two editions.
Thanks to his position on the day’s two hors catégorie climbs of Col de la Croix de Fer and Alpe d’Huez, Froome also secured the King of the Mountains title, the first British rider to do so since Robert Millar in 1984.
As well as runner-up spot behind Froome overall, Quintana also takes the best young rider classification. Peter Sagan (Tinkoff-Saxo) has taken the green jersey of point classification leader as he cannot now be beaten.
