Giro plays the least part in this for me.
the only way its interesting to me is to find look at some patterns and from that infer how doping works these days.
To me it seems theres a base level that lasts for 2/3rds of the season amd then there is is some wild short acting *** that makes you go ballistic in target races.
To me the fact that the season to season improvement is so big suggests that is a true and tried method and they just ramped up the dosage.
But the base level being so high that he dominates most of the races is something unbelievable as well.
