Stage 6 of Paris-Nice and Stage 4 of Tirreno-Adriatico are both live on the web right now. Paris-Nice can be seen here. Tirreno-Adriatico can be seen here. I'm feeling spoiled for choice.
Defending champion Alberto Contador, the best stage racer in the world these days, is currently leading the general classification in Paris-Nice, though Cyclingprof favorite Jens Voigt remains in the hunt. Meanwhile, sprinter Daniele Bennati currently leads the Tirreno-Adriatico, but it would be a massive shock if he held on for the overall victory, with riders such as Tom Boonen, Cadel Evans, and Edvald Boassen-Hagen lurking.
