Phil and Paul mentioned this today on OLN. This may be the first clean tour.
I agree with pete, the whole way Giros and TDFs are designed may have to change, as doping has been part of the sport, and never left, since the 50s.
However, LeGrand was once quoted as saying the perfect tour would only have one rider left.

Today's interview on OLN with Hamilton was truely pathetic, he and his wife now have changed the "I'm innocent" tune to "it's very, very complicated". He cheated, he got caught, what's so complicated? I hope they connect him with OP and kick his ass out of the sport for good.
