 As the peloton headed towards the penultimate climb , the Côte de Cherave , Huub Duyn ( Team Roompot ) attacked but was unable to build a lead , with Tony Martin leading the peloton on behalf of Kwiatkowski . On the climb , Vincenzo Nibali attacked ; he could not build a gap to the group , but did bring them closer to Visconti and Sánchez . Soon afterwards , Tim Wellens ( Lotto @-@ Soudal ) attacked , catching and passing the leading pair . Giampaolo Caruso ( Katusha ) attempted to follow ; he was unable to join Wellens and was recaptured by the pack soon afterwards .
