Tbh with Carapaz' luck Quintana would've won the Tour
I consider it inadequate to discredit another woman's or man's achievement that was built through years of hard work with one sweeping statement. Your post would be more honest if you would be so kind as to give us your definition of luck, in particular in the context of professional cycling.
My understanding ( and I would assume that of many others to) luck is the realization of one of several event that is associated with a low probability ( likewise if one or several event with high probability are not realized, etc.).
I have read here a few times now that Carapaz was "lucky, that Roglic and Nibali looked at each other".
Well, I have trouble with associating winning/losing a tactical battle with luck. I think we can all agree that Nibali and Roglic are not random number generators but rational agents in the race. When Carapaz attacked he forced the two leaders to make a hard choice in an instant. Now their reaction was basically the result of a calculus based on the following parameters:
- current strength at that moment
- estimation of strength and ability of Carapaz in that situation
- estimation of own ability to make up the last time on this or later stages
- Risk/reward of staying back/following/counterattacking
Now in hindsight we know that both probably misread the situation ( and that is assuming that they would have had the strength and 1 was not the primary reason that they stayed back). But in order to establish this as luck you would have to assume that the calculus with the same parameters would have lead to a different result if done several times and that the actual outcome was that with a lower probability attached to it. I'm not convinced of either. And Carapaz being the agent causing imposing this challenge on the two would make me even more hesitant to call it look.
Mind you, I am not saying that luck never is part of the outcome (it can even play a heavy role) but you need to try a bit harder if you want to have an honest and level debate.
