I purchased this off of e-bay for about six quid. It's a two DVD set which takes you through the seven different Tour de France races that Lance Armstong won, following his fightback from testicular Cancer. It's really worth a watch. I did the whole thing back to back. Watching any sort of professional cycling let's you study technique, how the riders sit in different terrain and conditions. I've since lent it to my neighbour. Going to put it back on e-bay and buy another one.
