Team Sky's Geraint Thomas extends Tour de France lead as Nairo Quintana wins 17th stage

Team Sky's Geraint Thomas extended his lead in the Tour de France as Chris Froome slipped out of second place on 17th stage won by Nairo Quintana.

Froome slipped back off the main group of contenders late on the climb to the summit finish on the Col du Portet before Thomas jumped clear of rivals Tom Dumoulin and Primoz Roglic, who started the day third and fourth in the general classification.

Thomas took third place on the stage behind Irishman Dan Martin, picking up a handful of bonus seconds to go with the time gained on the road.

That means Thomas now leads the Tour by one minute 59 seconds from Team Sunweb's Dumoulin, with Froome two minutes and 31 seconds back.

Quintana won the 65-km mountain trek from Bagneres-de-Luchon having attacked at the foot of the last climb up to the Col du Portet to beat Martin by 28 seconds.
