Doping occurs when an athlete uses prohibited substances or methods to improve his or her results in training and competitions. Doping has been an issue that has plagued professional cycling for years, and many Tour de France riders have been accused of using this practice to increase their performance. During the 2021 Tour de France, approximately 3.8 percent of riders committed anti-doping rule violations. This is a significant decrease from the 52.8 percent of riders in 2000.
