The 1984 Paris–Roubaix was undertaken in extremely muddy conditions, reducing the speed of the riders and making the race even harder than usual.

The race was characterised by a great deal of action early on, but the deciding move came with 45 kilometres to go.

At this point Sean Kelly went after two La Redoute riders who were out in front, Gregor Braun and Alain Bondue.

Braun was soon dropped and Bondue then crashed, and despite chasing hard, could not regain contact with the front two.

At the finish on the Roubaix velodrome, Rogiers had no chance against the dominant Kelly who easily won the sprint for his first Paris–Roubaix win.
