Maybe another bonus for Roglic but the break probably has a good shot. Someone like Rolland maybe, De Gendt might look for something easier. Zakarin has his usual issues with descents but will probably try anyway. GC top 10 should get a shake up at least. Pogacar probably won't be able to restrain himself, Jumbo will probably take a wait and see attitude. Quintana, Landa and others get another chance to show what they have. Be nice to see Quintana risk his position on GC and go all in but he probably won't. Never really been his style. I think they have to at least test Roglic's legs and Pogacar would be the obvious one to try. Whether he can continue to keep doing that until the TT remains to be seen. I thought Bernal showed some improvement on the previous climbing stage. Richie Porte's final chance for another top five GC result ? Losing a chunk of time here will mean the end for that aim. If he can stay in contact with riders like Landa on GC the time trial should move him up.
Unfortunately Zakarin is out of the race with a broken rib.
I think a large break group will form. Someone in this group will be around 8 - 10 minutes behind yellow jersey. And group will finish the race around 11 minutes before Yellow jersey so Roglič will loose it. In last climb Roglič does nothing, then Bernal attacks with Roglič and Pogačar following wheels. Then Pogačar goes and doesn't look back. Roglič again on his wheel, Bernal falls behind but catches them before finish.
Did you even check the GC? There's literally no one between 4 and 12 minutes behind Roglič...
