As the news broke today that four-time Tour de France winner Chris Froome had failed a drug test, many people are asking why professional cyclists are determined to destroy their own sport.
From Lance Armstrong to Floyd Landis to Alberto Contador, the sport is riddled with high-profile, successful riders who are drug cheats.
Froome's British team Sky were created to be a completely clean cycling team. "There’s no place for drugs in the sport and we like to think that we’re at the forefront of trying to promote clean cycling," Sky's boss once told The Guardian.
Now, once again, the sport is in disarray. Turns out riding a bike is more complicated than it seems.
