 The first major attacks came with about 60 km (37 mi) remaining: Kwiatkowski attacked with three teammates (Tony Martin, Julian Alaphilippe and Michał Gołaś), briefly gaining a lead of half a minute. Team Sky were able to catch them. After the next climb, the Col Saint-Roch, the same four riders attacked, with Tony Gallopin (Lotto – Soudal) following. They again gained a half-minute lead, while Sky had just one domestique left to help Porte and Thomas. Etixx – Quick-Step were unable to continue their pressure, however, on the Côte de Peille. Gallopin attacked after sensing that Kwiatkowski was vulnerable. Near the top of the climb, Porte and Thomas caught Kwiatkowski's group, then attacked them and left them behind. They were joined by several riders, including Simon Špilak (Team Katusha) and Jakob Fuglsang (Astana).
