2008 Giro d'Italia

The 2008 Giro d'Italia was the 91st running of the Giro d'Italia, one of cycling's Grand Tours. It began in Palermo on 10 May and ended in Milan on 1 June. Twenty-two teams entered the race, which was won by Spaniard Alberto Contador of the Astana cycling team. Second and third respectively were Italians Riccardo Riccò and Marzio Bruseghin.

Contador first took the race lead after the second mountain stage, to Marmolada, by finishing nearly fifteen minutes ahead of previous race leader Gabriele Bosisio. The race's overall classification had been headed for several days beforehand by Giovanni Visconti, who participated in a breakaway in the sixth stage which won him sufficient time to hold the race leader's pink jersey for more than a week. In the race's final week, Contador faced stern challenges from Riccò and defending Giro champion Danilo Di Luca. Though Contador did not win any stage, his performances were consistently strong enough to remain ahead through to the conclusion of the race.

Team CSF Group–Navigare appeared to perform quite well in the race, coming away with four stage wins and victory in the mountains classification and the Trofeo Fast Team. In August 2008, mountains classification winner Emanuele Sella was announced to have tested positive for methoxy polyethylene glycol-epoetin beta (better known as Mircera, an erythropoietin derivative) at an out-of-competition control held by the Union Cycliste Internationale (UCI). He subsequently admitted his doping, and named teammate Matteo Priamo as his supplier. Both riders were subsequently suspended. Though as of April 2010 no definitive positive results have come to light from samples taken during the Giro, retesting of those samples has reportedly revealed six to seven presumptive positives for Mircera. Riccò, who tested positive for the drug at the 2008 Tour de France, is among those suspected of having given positive tests in the Giro, as is Sella.
