This looks like a stage that everyone and their grandmother wants to win, and probably could. I mean, there are 50-60 riders who if they win the stage, we'll go, "Yeah I could see that happening".
Breakaway is probably about a 40% chance to succeed.
Of the GC riders I doubt that Carapaz will win the stage. Most riders are unpredictable, but one of the most likely outcomes is that Carapaz will finish comfortably in the second GC group (behind 1-4 riders), improving his position slightly overall. I see him racing conservatively here.
It wouldn't totally surprise me to see Ineos allow Porte to attack near the top if the breakaway is a caught, to get him a first GT stage win (though that's also wishful thinking).
Yates is not necessarily a better chance to perform better on this stage than Carapaz, but he is a far better chance to win the stage imo.
Lopez seems overrated; he is better later in GT's, yes?
Odds wise, Dumoulin is good value. If he's form is good, this climb should suit him. I'm warming to him as a stronger overall winning chance already too.
Hindley could also do well here, though in 2020 it was his third week that was strongest.
