Danilo Di Luca won the longest stage of the Giro d'Italia on Tuesday with a late solo breakaway and added to his overall lead. The 2007 winner attacked on a short climb three kilometers from the finish of the 10th leg. He clocked 6 hours, 30 minutes, 43 seconds over the 262-kilometer route from Cuneo to Pinerolo, passing through the Sestriere ski resort. Franco Pellizotti crossed second, 10 seconds behind, and Denis Menchov was third with the same time. Di Luca now holds a 1:20 advantage over Menchov in the overall standings. He began the day with a 13-second lead over Thomas Lovkvist, but the Swede couldn't keep up on the last climb and dropped 1:39. In addition to time gained, Di Luca also earned a 20-second time bonus for his victory. Defending Tour de France winner Carlos Sastre finished fourth, 10 seconds back, while other overall contenders Ivan Basso and Levi Leipheimer crossed 29 seconds after Di Luca. Lance Armstrong finished 13th, also 29 seconds back. Di Luca's victory celebration was muted out of respect for a motorcycle rider who died in a crash heading toward the start of the stage. Fabio Saccani, a 69-year-old photographer, was riding in his 32nd Giro. He also worked the Tour de France 11 times for cycling photographer Roberto Bettini. The tragedy came three days after Spanish rider Pedro Horillo Munoz ended up in a coma for 24 hours and had severe injuries after falling 60 meters off the side of the road on a downhill stretch. A minute of silence will be observed for Saccani before the start of stage 11 on Wednesday, a 214-kilometer mostly flat leg from Turin to Arenzano on the Ligurian coast.
