Doping at the Tour de France

Use of illegal substances by cyclists in the Tour de France

There have been allegations of doping in the Tour de France since the race began in 1903. Early Tour riders consumed alcohol and used ether, among other substances, as a means of dulling the pain of competing in endurance cycling. Riders began using substances as a means of increasing performance rather than dulling the senses, and organizing bodies such as the Tour and the International Cycling Union (UCI), as well as government bodies, enacted policies to combat the practice.
