I definitely understand that, I just have a gut feeling today is going to become a day to stick the knife in at least one of the top 3, then the race dynamic becomes "Full speed ahead, and worry about tomorrow tomorrow." Note, my gut has let me down before... ;-)You have to remember they all know there is tomorrow as well.
Going deep and risking it all on a long range attack today, may cost them the Giro tomorrow.
If gaps were 3-4 minutes we'd see long range today, but gaps being what they are I don't think so.
Mind you I'm talking about the top 4 - below that people will try.
