Major doping scandals on the Tour de France

The world of cycling has taken a backseat while the relationship between cyclists and anabolic steroids has taken the front-seat these days.

Big names such as Lance Armstrong and Alberto Contador have been accused of doping in sports.

From Reuters.com:

* 2010 - Alberto Contador, winner of the 2010 tour, tests positive for the banned anabolic agent clenbuterol during the race. He is cleared by the Spanish cycling federation (RFEC), but the International Cycling Union (UCI) and the World Anti-Doping Agency (WADA) appeal. Contador's CAS June hearing is postponed, allowing him to enter this year's race.
-- If found guilty, Contador, who has denied any wrongdoing, would face a possible two-year ban and be stripped of his 2010 Tour title.
2011 - Seven-time Tour de France winner Armstrong is again accused of taking banned substances. His former team mate Tyler Hamilton tells the U.S. television program "60 Minutes" he witnessed Armstrong inject himself with a blood-booster during the 1999 Tour de France won by Armstrong. Armstrong has always denied taking banned substances and has repeatedly had to fend off accusations despite having never failed a drugs test.

The list of names linked with performance enhancing drugs does not end here and includes big names like Richard Virenque, Floyd Landis, Jan Ullrich, Ivan Basso, Alexandre Vinokourov, Riccardo Ricco, and Bernhard Kohl to name a few.
