The problem with such a relatively tight GC, especially from 3rd to 7th, is that riders will just hope their rivals have a bad day, knowing a bad day on these climbs means minutes (and not just seconds like in other stages). They probably believe beating Roglic and Pogačar is impossible at this point and will likely be very pleased with a podium spot.
At the same time the riders with the potential for a long range attack, like Quintana and Bernal, are so banged up that I'd be surprised to see them trying. Quintana has historically had some incredible climbing performances even when his level wasn't top notch over the course of three weeks, but he was never as injured as he's now.
Would be nice to see him attack on Madeleine, possibly with G. Martin and a couple strong domestiques from other teams, but I wouldn't count on it. And Jumbo would likely keep riding tempo and reel them in eventually.
Realistically speaking, we should hope both De La Cruz and Polanc survive Madeleine and feel good enough to drill it from the bottom of Loze. I'm not counting on Bahrein or Astana doing this.
