Trek - Segafredo was in charge of the case as the race entered the many cobbled sectors - 18 in total. Marianne Vos suffered a puncture quickly after, as Daniek Hengeveld went up the road in the breakaway to lead the race alone. The race remained rather consolidated until 51 kilometers to go, there Lotte Kopecky attacked in the peloton and split the group as the race really kicked off and the riders in front still had a very large gap of around 4 minutes.
Hengeveld was caught with 44 kilometers by her breakaway companions, whilst soon after in the peloton many riders went down whilst on the attack. A chaotic situation, the likes of Kopecky, Wiebes, Longo Borghini and others hit the deck, completely disrupting what started to be an efficient chase. What was a race of attrition then saw the break and peloton both lose riders slowly, without any meaningful attack splitting the race.
However, despite the great efforts of the breakaway, the riders in the peloton began to close the gap almost completely. The cobbles failed to make decisive differences, as a group of seven riders left the final proper cobbled sector of Willems à Hem with 10 seconds over the leftovers of the peloton: Femke Markus, Eugénie Duval, Marta Lach,
Katia Ragusa, Alison Jackson, Marion Borras and
Marthe Truyen.
The gap was so small yet so big. Fatigue was felt as much in the chasing group as in front. Repeated attacks and occasional strong pulls saw the gap holding steady into the final kilometer. Markus dramatically crashed already inside the velodrome. The breakaway managed to survive, and Alison Jackson was the fastest in the sprint. Katia Ragusa and Marthe Truyen completed the podium.
