Hitch is pretty much saying he was doped in 2008 on 8 stages of the TDFWalkman said:Hater much?
You do know that people can improve right? And it's not like every pro cyclist are 100% dedicated and training perfectly their entire careers. People can improve significantly even late in their careers by applying the right (non-doping) methods.
And to clarify, not saying Froome is clean, but your statement is showing a lack of understanding of the body and of the athletes. I'd say for most of the riders, the limiting factor is their dedication and will to improve. There is a huge difference, even among pro athletes, with regards to how serious they take their training and how much they dedicate to improve.
Which imo is a pretty dumb statement from him, perhapas he was exagerrating for effect, but to be honest, such exagerrations is pretty tiresome, but hey its Froome and the clinic so who cares
