This Tour probably isn't going to be won on bonus seconds, and even if it technically was, then that doesn't mean that team energy was used in the most efficient way.
So I don't understand suggestions that UAE should work just to keep a breakaway within striking distance.
UAE should do nothing but save energy with their riders and Pogacar, only making extra efforts when the specific purpose is to put time into Vingegaard, head to head vs. Pogacar.
If the break is 15 minutes clear at the foot of the final climb tonight, so be it. The break should be totally invisible to UAE.
If Pogacar is feeling good, then the team might work for 20kms before the final climb (perhaps up to 50kms before depending on how the team and Pogacar are feeling, and on other factors such as pace setting from other teams).
Majka goes all out on the first km, attempting to reduce the peloton to single figures. Then Pogacar gives it everything he has got. Maybe he gains thirty seconds. Anyway, time gained by properly distancing a rival is time gained in the mental game too.
