On Quintana:
We know he was born, raised, & developed physiologically at 2820 mts a.s.l.
We know when he was a child he used to go to school by bicycle climbing a cat 3 "every single day of his scholar calender.
We know his prior record before turning professional
We Know he was touted by many experts to become "the next big time"
We know his performances are "within human capacity"
those facts are "irrefutable" & proof of a "clean rider"
However......
The only aspect alone that I could have slight doubts on Quintana is that he rides for Unzue's team,- but then I ask- how come Valverde has not become a multiple GT winner under his guidance- if the dope was the answer??
bottom line- he could well be doping- as part of being Pro-cyclists. Does he rely on dope to succeed? don't think so. Perhaps the dope gets the very edge of his abilities, but never "transforms his skills" into an "alien"- per say....
having stated that-I will be the first one to call Quintana out on this thread if I ever watch him doing this sort of performance:
