Bernal really killed the race today, Sivakov lost a huge amount of time, Carboni also over 5min.
Bernal has a strong team around him Sosa is his teammate at Androni and from what I've seen he's friends with Dani Martinez.
Unfortunately, Bernal has no interest whatsoever in winning all the three mountain stages, as he gives priority to GC. Of course, he won't say no to another victory, but it's not a goal of his. Therefore I'd say there is a big chance of the break staying away the next two days (unless the Australians still think they're still in this), as long as there aren't any dangerous riders up the road.
