It's a really bad route for Evenepoel, against a field he would have struggled to beat even on last year's route, and with form that seems just a tad less strong than last year's. Depending on the route of the latter, this might actually be a taller order for him than next year's Tour will be. If he does actually win this or come close, it's definitely time to start talking about a future Tour win as an expectation rather than a possibility, but I don't think he will.
As for Jumbo, Vingegaard should be a bit weaker than at the Tour, but he has room to slide compared to that level. I still expect him to assert his status as the team leader on Javalambre - Roglic will be good, but not good enough. And once he's in the lead, he basically never gets toppled. Hard not to see him as the biggest favourite here, and tbh I think the odds of a great race would be better if he wasn't here.
Ayuso, assuming he's fully recovered from the Ordizia crash, looks ready for the next big step. I think he'll give Vingegaard more trouble than anyone else on the climbs, but it's too early to expect him to match him blow for blow all day, every day for three straight weeks. Would be disappointed if he doesn't make the podium, though.
Thomas... I just can't see it. Let's also not forget he's never done two GT GCs in the same year.
Everyone else listed has the same chances of winning, and that includes Carapaz. Mas will need to be at his very best to stand a chance of another podium and the signs aren't exactly great, the rest can't hope for more than a top-5 here.
So I'll go with:
1. Vingegaard
2. Ayuso
3. Roglic
