 A breakaway formed within the first 10 kilometres (6.2 mi) of racing. There were seven riders in the break: Thomas De Gendt (Lotto – Soudal), Mike Teunissen (LottoNL – Jumbo), Brice Feillu (Bretagne – Séché Environnement), Jérôme Baugnies (Wanty – Groupe Gobert), Reinier Honig (Team Roompot), Daniele Ratto (UnitedHealthcare), and Pieter Vanspeybrouck (Topsport Vlaanderen – Baloise). The breakaway initially built an eight-minute lead, with De Gendt leading the group over the climbs. The main peloton was led principally by Movistar and Team Katusha.
