Quintana had lost even more time to the Dutchman – 31 seconds in total – and when Dumoulin, his typically smooth time trialling technique clearly unaffected by his efforts in the mountains, barely missed a beat on the second part of the course, it was clear the maglia rosa was all but his.
Dumoulin did lose nine seconds over the final part of the course – guaranteeing a tearful Van Emden would win the stage – but as far as the general classification was concerned, the gap to his rivals was only going up.
Quintana’s efforts were clear as he almost over-cooked a corner – taking every risk he could – but it was ultimately not enough to stop Dumoulin.
Nibali finished 13th on the day, 54 seconds slower than Dumoulin, while Quintana was 1’24” slower – both big efforts, and enough for third and second respectively – but the day, the maglia rosa and the senza fine trophy belonged to the Dutchman.
