teammate Raymond Riotte, after Riotte was in a group that escaped. In the eighth stage, Riotte lost considerable time, and Pingeon was back in the lead. On that stage, Raymond Riotte lost more than 11 minutes, also because of a fall and mechanical problems, and announced that he would ride the rest of the Tour in support of Pingeon. Pingeon gained a few seconds in the ninth stage after a split in the peloton. In the tenth stage, Poulidor helped Pingeon over the major climbs, and after that stage Pingeon had a margin of more than four minutes over the next rider, Désiré Letort from the Bleuets team. There were few changes in the general classification in the next two stages. The thirteenth stage was run in hot weather, and featured high climbs. During the climb of the Ventoux, Tom Simpson died. Unaware of what happened behind them, Jan Janssen won the stage, closely followed by Roger Pingeon, who extended his lead. The riders in the peloton decided to ride the fourteenth stage in dedication of Tom Simpson, and let his teammate Barry Hoban win the stage. In the sixteenth stage in the Pyrenees, Julio Jiménez won back a few minutes, and was now in second place behind Pingeon, 123 seconds behind. In the twentieth stage, with a finish on top of the Puy-de-Dôme, Jiménez won back some more time, and was now 1 minute and 39 seconds behind Pingeon. This was not enough to put Pingeon's victory in danger; the Tour ended with an individual time trial, and Pingeon rode it much better than Jiménez, and won the Tour de France of 1967. Doping After the death of Tom Simpson on stage 13, there were accusations of doping use. The organisation decided to increase the doping controls, not only in the Tour but also in the simultaneously run Tour de l'Avenir. The Tour de France gave no positive tests, but several riders from the Tour de l'Avenir were disqualified. Classification leadership and minor prizes There were several classifications in the 1967 Tour de France, two of them awarding jerseys to their leaders. The most important was the general classification, calculated by adding each cyclist's finishing times on each stage. The cyclist with the least accumulated time was the race leader, identified by the yellow jersey; the winner of this classification is considered the winner of the Tour. Additionally, there
