He did exactly what he should have to limit losses. This does bode poorly for the remaining mountain stages, though. It's going to get harder and his team isn't likely to be with him as much as they should be.He has done this before. He is weakest when there is a sudden change of tempo when he's not his best. Afterwards, he's usually quite good at limiting the damage, as he again showed here. A weakness, partly offset by a strength.
Still....it's a long race.
