Doping
In total, 110 doping tests were done. Three cyclists were penalized for doping offences, all tested after the sixteenth stage:
- Antoine Guttierrez, for attempt of fraud
- Michel Pollentier, for attempt of fraud
- 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.
