The early break was composed of Florian Vachon (Fortuneo-Samsic), Jérôme Baugnies (Wanty-Groupe Gobert), Loïc Vliegen (BMC), Anthony Perez (Cofidis), Mark Christian, Casper Pedersen (both Aqua Blue Sport), Paul Ourselin (Direct Énergie), Antoine Warnier (WB Aqua Protect Veranclassic) and Mathias Van Gompel (Sport Vlaanderen-Baloise).
The arduous pace also meant that the peloton began to lose riders at a steady rate, dropping off the back as the 2018 edition of Liege-Bastogne-Liege devolved into a race of attrition behind.
A series of attacks opened up the race, with Phillipe Gilbert (QuickStep Floors) and Sergio Henao (Team Sky) trying to get away on the early slopes.
There was a mix of hard-riding by Jungels and messing around in the elite chasing group behind, with attacks from Dan Martin (UAE Team Emirates) and Alejandro Valverde (Movistar), as well as a general lack of cooperation, causing the momentum to stall.
Jelle Vanendert (Lotto Soudal) put in a massive attack from the chasing group, distancing himself from the pack and cutting the escaped Jungels gap in half by the top of the climb.
Many attacks tried to go clear to chase down the escapees, but Romain Bardet (AG2R La Mondiale) and Michael Woods (EF Education First-Cannondale) were the only ones to get away to try and track down the riders ahead of them on the road.
Behind him, Vanendert exploded on the final section of the last hill and was passed by the two chasers and the group, with Woods outsprinting Bardet for second place.
