Chris Froome extends Tour lead as Dan Martin remains 9th

Froome's rival Nairo Quintana appeared to wave the white flag today.

Chris Froome is closing in on a third Tour de France title after extending his lead in the yellow jersey while Russian Ilnur Zakarin won stage 17 to Finhaut-Emosson.

As Zakarin was celebrating his first Tour stage victory from the day's breakaway, Froome latched on to Richie Porte's late attack to ride clear of his rivals and build a cushion of almost two-and-a-half minutes.
