well, today, sagan in one second looked fresh and destroyed everybody but stybar and piti, few minutes later, direct look at him and I knew he's done, same face as in the last years PR, where I knew 20km that's it for him.
Now the possible reason. He clearly has been very self confident about his strength, if he wasn't feeling well he would tried to keep it together until the finale. The attack was not "attack of desperation" as in PR last year.
I hope that he just hadn't either water or some nutrition with him as some were proposing.
What i am afraid of, that the reason is a little bit elsewhere. In slovak media there was mentioning, that sagan has been riding in Oman on anthibiotics, which might have been a very bad idea in those temperatures. Illnes and anthibiotics can be very tricky for human body in normal condition, the more it's stressfull for heart and other organs in 40 degree celsius and actually racing. I am really afraid, that monstrous damage might have been done there and it come to light today. If so, this season lost would be quite success, cause his entire career might be in danger.
