1985 Paris–Roubaix was ridden on the 14th of April in rainy conditions.
At one point, former three times winner Francesco Moser looked the serious contender, but a crash due to a hole between cobbles and a slow repair of his equipment eliminated Moser from the final.
About 15 kilometres from Roubaix, Marc Madiot escaped from an eight-man group with among others defending race winner Seán Kelly. Madiot held on and entered the velodrome in Roubaix on his own to win. Bruno Wojtinek, leaving the chase group some two kilometres from the line, finished second, cementing a French double. Seán Kelly and Greg Lemond were the next riders home, having avoided a crash just as the chasing group was entering the velodrome in Roubaix."
