If Bjarne Riis got up 2 hours earlier than everyone else, it was probably because he understood that sleeping an extra 2 hours with 60% hematocrit he would risk the blood clogging in his veins.
It is likely though that had 2013 Walsh been embeded with Bjarne he would have put it down to dedication.
Just like he ignores that training longer hours than everyone else is usually a result of doping, because doping allows for the body to recover and put out those extra efforts, whereas someone who is clean, if they train those same hours, no matter how talented they are, are actually causing themselves more harm than good.
