to bonus seconds in an intermediate sprint. At the finish of that last, Sercu finished first in a sprint, but he had blocked the way of Gustaaf Van Roosbroeck, so the jury decided to set him back, and the second rider to finish (Merckx) was declared winner of the stage. Normally, a rider penalized for blocking another rider during a sprint would be set back to the last place of the group that he finished in, but that would have meant that Sercu would have not only lost the stage victory to Merckx, but also the points classification. The jury then declared that only three riders were really sprinting for the stage victory, so Sercu would be set back to the third place; this enabled him to keep his victory in the points classification by 13 points. Doping Cyrille Guimard, who had won the first part of stage eight, tested positive for piperidine after stage thirteen. Three other cyclists tested positive:Claude Tollet, for amphetamine; Daniel Ducreux, for piperidine; Carlos Melero, for piperidine. Classification leadership and minor prizes There were several classifications in the 1974 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 1974. 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 1974, this classification had no associated jersey. For
