 The first rider to set off in the race was Daniel <unk> ( Bretagne – Séché Environnement ) . Dylan van Baarle ( Cannondale – Garmin ) was the leader for a significant period , with a time of 8 ' 04 " . The lead was briefly held by Giacomo Nizzolo ( Trek Factory Racing ) and Tiago Machado ( Team Katusha ) . Their times were beaten by Dennis , who recorded a time of 7 ' 40 " . Dennis held the lead for an hour and a half , until he was beaten by Michał Kwiatkowski by less than a second . Kwiatkowski 's time was enough to beat all the other riders . He therefore took the yellow jersey of the overall leader , as well as the green jersey of the points leader and the white jersey of the best young rider . The absence of categorised climbs meant that no polka @-@ dot jersey was awarded .
