Olav Kooij (Jumbo-Visma) took his second victory at the 4 Jours de Dunkerque, this time winning the stage 4 reduced-bunch sprint in Achicourt.
The Dutchman was part of a large, late-race group that split over the last climb and then caught the day's breakaway. His Jumbo-Visma teammates led the race into the closing kilometres, where Kooij won the sprint ahead of runner-up Gerben Thijssen (Intermarché-Circus-Wanty) and third-placed Milan Fretin (Team Flanders-Baloise).
