In what can only be described as one of the most surprising things in cycling all season … Nairo Quintana actually attacked! In fact, he was so committed to this attack, he won the tough 65km stage with a summit finish on the Col du Portet. While he was doing that, Sky whittled down the bunch of favourites until they even whittled down Chris Froome. Geraint Thomas put in a commanding performance against the attacks of Tom Dumoulin and Primoz Roglic to extend his margin to 1.59 on second placed Dumoulin and 2.31 on his teammate Froome. Roglic is now only 16sec away from that third step.
