1978 жылғы Тур де Франс: Допинг дауы мен Хинальдың жеңісі

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
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.

During the prologue, held in the Netherlands, the weather was bad. The four top places were taken by Dutch cyclists, with Jan Raas the winner. The team directors then had a meeting, and all but the manager of Raas' team voted to request the Tour directors to not count the results from the prologue for the overall classification. The directors agreed, so the prologue results did not count. Jan Raas was still given the stage win, but he was not recognized as race leader, so he was not allowed to wear the yellow jersey during the first stage. The winner of the previous year, Bernard Thévenet, was allowed to wear the yellow jersey, but he refused. In that first stage, Raas and his team were full of anger. Raas escaped close to the finish, and beat everybody by a second, thus becoming the race's leader after all. Raas lost the lead in the third stage. The fourth stage was run as a time trial. The TI–Raleigh team was specialized in this, and they won the stage. Klaus Peter Thaler of the TI–Raleigh team became the new leader, thanks to the bonification seconds. Hinault beat Zoetemelk in the time trial in stage eight. The Tour officials canceled the stage. Antoine Guttierrez, for attempt of fraud; Michel Pollentier, for attempt of fraud; and José Nazabal. Nazabal had already anticipated the positive result, and had left the race before the eighteenth stage. Guttierrez and Pollentier were removed from the race and banned for two months; Nazabal was set back to the last place of the stage, received ten minutes penalty time in the general classification, a fine of 1000 Swiss Francs and one month provisional suspension.
