Armstrong back on a bike

Lance Armstrong, who broke his collarbone in the Vuelta a Castilla y León, was back on a stationary bike on Saturday. Armstrong pedaled for half an hour, he announced on twitter.

Despite a fairly long scar from the surgery, Armstrong was smiling as he pedalled, just three days after his surgery. Armstrong still aims at participating in the Giro d'Italia (May 9-31), despite the loss of training.
