The Prologue of the Tour is underway as I type (follow it here). It takes place in London. Will doping continue to detract from this fantastic sporting event? I hope not. It's three of my favorite weeks of the year.
I follow most of the event on Sportsline's Tour page, and their live updates found here. I'm going to be checking in on Versus.com as well, which seems to have a lot of good info. It seems that Vs is the new Outdoor Life Network, which televised the Tour. Now on Vs there should be live updates, video clips, and more. Also check out the TdF live tracker.
