The 1978 Tour de France was the 65th edition of the Tour de France, one of cycling's Grand Tours. It took place between 29 June and 23 July, with 22 stages covering a distance of 3,908 km (2,428 mi). The 1978 Tour had a high-profile doping case when Michel Pollentier was caught in an attempt to cheat the doping test, after he had won the 16th stage to Alpe d'Huez, and had taken the lead in the general classification. Pollentier left the race, and the overall victory became a battle between Joop Zoetemelk and Bernard Hinault. In the end, it was won by debutant Bernard Hinault, for the first of his five victories. The points classification was won by Freddy Maertens, and the mountains classification by Mariano Martínez.
