The 2017 Dwars door Vlaanderen is a road cycling one-day race that took place on 22 March.

[2][3] The race was won by local[4] rider Yves Lampaert – riding for the Quick-Step Floors team – who soloed away to the victory after making the race-defining split along with teammate Philippe Gilbert, Alexey Lutsenko from the Astana team, and Orica–Scott's Luke Durbridge.

It began with a long flat section that took the riders generally east from Roeselare and into Waregem; it then left the town and went south.

At Avelgem, the course turned back east again to cross the first climb, the Nieuwe Kwaremont, after 92 kilometres (57 mi).

After the next climb, the Valkenberg, the course turned back west towards the finish, with 70 kilometres (43 mi) remaining.
