Alberto Contador has been stripped of his 2010 Tour de France title and banned for two years after sport's highest court found him guilty of doping.

Spanish cyclist Alberto Contador of Team Saxo Bank is racing in Mallorca on the eve of the long-awaited verdict on his doping case by the Court of Arbitration for Sport (CAS).

Belgian Tom Boonen won the opening stage of the 2012 Tour of Qatar earlier today finishing four seconds ahead of Adam Blythe of Great Britain.

Federal prosecutors dropped their investigation of Lance Armstrong today, ending a nearly two-year effort aimed at determining whether the seven-time Tour de France winner and his teammates participated in a doping program.

Spanish Team Movistar captain Alejandro Valverde says his strong performance in the 2012 Santos Tour Down Under has relieved some of the pressure after returning from a two-year doping ban.

It was another jam-packed week with the cyclo-cross world championships, delays in the Contador case and of course Twitter.
