ultimately no one really cares about one week stage races.
also, as mentioned, he has so often been injured, recovering from injury, or health issues (TdS 2023, post-COVID).
also, if the one week stage races regularly had even a 20 km ITT (as they used to), he would have won many.
frankly, I don't care about 1-week stage races -- so often simply tune-ups for the GTs.
