 This quintet held an advantage of approaching three minutes , as they headed towards the final climb in the treacherous conditions that had been prominent throughout the stage . Wellens attacked at the foot of the climb , and managed to acquire a gap over around 30 seconds halfway up , but had been tiring quickly . This fatigue allowed De Marchi to rejoin him , and ultimately pass him on the road . Team Sky , leading the peloton in protection of the overall leader Chris Froome , were setting a fast pace in the group , and the pace forced Michael Rogers ( Saxo – Tinkoff ) to be distanced , putting his third place overall under threat . Froome and team @-@ mate Richie Porte soon gained ground off the front of the peloton , further securing the duo 's one @-@ two finish in the overall standings . They set off in chase of De Marchi , but he ultimately prevailed for his first professional victory , finishing 24 seconds clear of the nearest rider . Froome finished second , ahead of Garmin – Sharp 's Andrew Talansky , who caught Froome and passed Porte in the closing metres ; Froome thus secured the overall lead , missed out on the points title by two points to Meersman Rogers faded to sixth overall , which handed Daniel Moreno ( Team Katusha ) the final place on the podium .
