Mahé, Jacques Moujica and Frans Leenen were desperate to get inside the stadium and cross the finish line before the next riders arrived.
Mahé acknowledged the crowds, took the bouquet, did a lap of honour and then headed to clean himself up at the track's showers.
A few minutes later the bunch arrived using the correct route and Serse Coppi, brother of the more famous Fausto, won the sprint for what was assumed to be, the minor placings.
When the Coppi brothers heard about Mahé's unconventional approach to the finish they protested, demanding he be disqualified or demoted and that Serse be named as the winner.
The final outcome - to reinstate the race and declare André Mahé and Serse Coppi as joint winners - was not popular with either side.
"[2] Mahé made his mark in the professional peloton in his second year, 1946, by winning the Tour du Finistère and coming third in the classic Grand Prix des Nations time trial.
When the company moved to Compiègne in northern France (coincidentally, now the starting point of the Paris–Roubaix) he relocated to that area.
