Primoz would need to be in a very good form, a significant progress is needed, even compared to pre stage 8 PN level. 5 km at almost 10% is Skeletor's territory actually. He's shown some amazing VAM on 10-15 min climbs already. Those climbs aren't that long but they are long enough to be mostly in aerobic zone plus they are repeated one after another.
Primož with his best 2023 form follows Vinge on Krabelin. I'd bet on that. But the question is of course whether he has the form.
I'll venture he'll be better than in Paris-Nice. The rest... is up to where he stands versus the others. If he isn't better than Paris-Nice, then there's probably cause for some concern, i.e. after Itzulia he does Liège, then it's an altitude camp, then Dauphiné, then Red Bull give them their new kit (apparently) & it'll already be time for the July circus around France.
Aka the Tour isn't that far away.
