Didn't they offer some kind of web package for viewing daily stages of the Giro (and maybe Vuelta) this past year? Not that one would want to sit at a pc monitor and watch 3 hrs of racing but, if you were really desperate.... Don't know if you had to watch live or you could watch a stream later, when convenient. I agree that 60/90 minutes per day would be interesting, more so than bull riding repeats but, I guess that sells?
In some respects, the Giro and Vuelta are more interesting to follow just because, with smaller local teams involved (maybe not so much with the Pro-Tour version), you really had some wild cards that could reek havoc with the plans of the big squads. We'll see how things play out this year.
