The top of the GC has turned into a doping farce. At the top, well, there's the saying, "There's something rotten in Denmark..." Then we have the members of the Disco doping brigade, who come on the boil just at the right time.
I think there is only one rider to pull for, and that's Soler going for the polka dots. He may be doping too, but he and his team certainly don't have the resources to purchase the kindof juice the others are on.
