The 181.3 km final stage from Saint-Omer to Dunkerque was the flat sprint the GC men needed to neutralise, run at a blistering 45 km/h average. A major crash early in the stage caught up race leader Laurence Pithie, who needed a bike change but rode on with only minor injuries. The drama wasn't over: a mechanical four kilometres from the line forced Pithie onto team-mate Callum Thornley's bike, but he made it safely into the bunch to protect his seven-second lead. At the front Red Bull-BORA-hansgrohe ran the perfect lead-out, Danny Van Poppel delivering Jordi Meeus, who powered to a dominant win ahead of Van Poppel himself and Gianluca Pollefliet (Decathlon). It was Meeus's second win of the season and the bookend to a week Red Bull began and ended with a stage victory.

With no breakaway threat and the bunch together, the GC was settled: Laurence Pithie won the 2026 4 Jours de Dunkerque overall by seven seconds from Natnael Tesfatsion (Movistar) and eleven from Rasmus Tiller (Uno-X). Stan Dewulf (Decathlon, +14s) and Liam Slock (Lotto-Intermarché, +14s) rounded out the top five. Pithie also took the points and young-rider classifications, completing a clean sweep of the race's individual jerseys in his first professional stage-race victory; he succeeds Samuel Watson on the palmarès.
