That climb should be interesting. The weather looks like it will be quite nice today too!
Anyway yesterdays stage was very interesting. It looked like Blanco were set for one-two attacking, Only Nordhaug was dropped on the first climb.

As Dekker_tifosi mentioned they are probably in a heavy training period preparing for July, so considering this I was very impressed with Mollema and Ten Dam. Mollema came in third and Ten Dam worked hard in the group.
The Norwegian TV2 commentators said it looked like Nordhaug had been training too heavily, so he might need to be a bit more careful. He is probably so set on the Tour that his enthusiasm got the better of him.
Edvald performed as I hoped, I think he has put much more emphasis on his climbing, and that is starting to show.
I was really impressed with Sondre Holst Enger He is born 17.12.1993, so he is 19,5 years old.
He gives me the impression of having a sprinters attitude, very offensive in his attitude. Unlike Edvald who is more defensive and shy. I think the sprinters need to have a bit of an attitude to become really good. In Norwegian we tend to use the term vinner skalle or winners head(see Northug as an example).
But what surprised me was his climbing ability, that was really impressive, and in the end he even sprinted for placings, and just nabbed 4th!
Unless the interviewer was huge, Sondre doesn't look to be that tall either. Perhaps he is built like a climber, but can still sprint like a sprinter?
Also Kristoff seems to continue his progression. He was able to rejoin the group on the decent of the first climb, before being finally dropped on the second climb.
Finally I was really impressed with Ben Swift and Josh Edmundson. The kept the tempo up on the first and most of the second ascent. That was very impressive!
Ps: Here are the results of the stage:
