I don't think the odds for Almeida and Ayuso are all that great compared to what the bookmakers think. Vuelta routes are terrible for Almeida compared to Giro/Tour ones, and Ayuso has a spotty track record and probably also a suboptimal preparation given that he wasn't scheduled to do this race until a few weeks ago.
A fully recovered Landa would probably have been my favourite for #2, but based on Burgos I doubt we get one. So for now I'll add Carapaz and Almeida to the obvious Vingegaard, but I kind of expect someone not yet listed by PCS to make the podium.
