Just to add to that Le Mond (American despite the name sounding French) and Hinault were team mates and the year before, Le Mond who probably could have won that years Tour, agreed to help Hinault win his fifth Tour - and thus make him the equal all time best rider ever in the Tour (up to that time anyway) on the condition that Hinault would help him the following year.
Hinault obviously thought that it was his last shot of becoming the outright best rider in the Tour ever, so 'attacked' Le Mond - in theory his team leader - at every opportunity he got throughout the race.
Le Mond was the younger and stronger rider by that time and just managed to beat Hinault and become the first English speaking AND non eueopean to win the Tour.
At that time all the cycle teams were very much euro-centric and very much out to stop Le Mond winning - even his own team too!
Le Mond was a great rider and would have won many more Tours - he only won two more - but for the fact that after winning this Tour against Hinault - he accidentally got shot!
I tell you, cycling is like no other sport, you never know what is going to happen next.
If cycling was a film, everyone would think it was too far fethched to be real - but it is!
I could go on and tell you about the amazing fued between Le Mond and Lance Armstrong but that's more to do with the Armstrong 'story' than with Greg himself.
Cost him his business though.
