34. Meat Problems
Alberto Contador was one of the best cyclists of his generation. Of course, this meant that he failed a drug test because all of the best cyclists do this. Why would he be any different? He won multiple Tour De Frances, Giro D’Italias, and Vuelta Espanas in a glittering career. However, he tested positive for clenbuterol in 2010 after the final race of the Tour De France.

As a result, he lost the title and suffered a suspension. Contador claimed that it was a case of contaminated meat. He says that the affected food was brought from Spain to France and that several riders ate it. Furthermore, he said that the UCI said to his face that it was a clear case of food contamination. But this didn’t stop World Cycling from stripping him of all his major titles for that year.
