After the finish in Paris, Merckx gave the green jersey that he received for winning the points classification to Guimard, who otherwise would have been the winner of that classification. Doping Guimard had been treated by Bernard Sainz. After Guimard left the race, there were rumours that Guimard had been using doping in the last days of the Tour; to end these rumours, he requested that after the eighteenth stage, he would also be checked for doping. In 2000, Sainz wrote the book "The stunning revelation of Dr. Mabuse", where he denied that he was responsible. Later that year, Eddy Merckx finished second in the athlete of the year poll, behind Mark Spitz. Classification leadership and minor prizes There were several classifications in the 1972 Tour de France, three 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 was a points classification, where cyclists got points for finishing among the best in a stage finish, or in intermediate sprints. The cyclist with the most points lead the classification, and was identified with a green jersey. There was also a mountains classification. The organisation had categorised some climbs as either first, second, third, or fourth-category; points for this classification were won by the first cyclists that reached the top of these climbs first, with more points available for the higher-categorised climbs. The cyclist with the most points lead the classification, but was not identified with a jersey in 1972. Another classification was the combination classification. This classification was calculated as a combination of the other classifications, its leader wore the white jersey. The fifth individual classification was the intermediate sprints classification. This classification had similar rules as the points classification, but only points were awarded on intermediate sprints. In 1972, this classification had no associated jersey. For the team classification, the times of the best three cyclists per team on each stage were added; the leading team was the team with the lowest total time. The riders in the team that led this classification wore yellow caps. In addition, there was a combativity award, in which a jury composed of journalists gave points after mass-start stages
