I'd forgotten that Froome finished 50 seconds down in the opening ITT in the 2015 TDF. Two stages later, thanks to the Mur de Huy, he was in yellow. The climb at the end of stage 4 looks like a poor man's Mur; depending on if he's fully recovered from the crash and how well he's climbing, he might claw back some of his deficit on some of the contenders ahead of him. He won't be able to gain a lot of time even in the best case scenario, but based on the way he's scrambled for a few extra seconds in the early stages of the past two Tours, I think he will regard it as important not just to finish at the same time with the others.
