For now Il Lomabardia is still on his schedule but I remember Lefevre also saying Remco would do only races close to home the rest of the season.Maybe, maybe not.
The main goal was the Olympics, and it's hard peaking for that en route to La Vuelta. It's not a training race either. What are you gonna do there?
He's mainly aiming for the Worlds it seems, but I wouldn't have minded seeing him in some more climbing races, though La Vuelta is very likely too much.
Also, for the Giro having enough ITTs, it depends much more on his climbing than the route. You need to be within ~2 minutes for 30km ITT more or less to make a huge difference.
Is he planning on doing the Italian fall classics?
I just think finishing a GT would make Remco stronger, but being Remco it wont be easy to like ride the Vuelta easily. People will expect him to shine again even if he would say it was only a Vuelta to become stronger.
I just think they are not a lot of other suitable options. A type of tirreno, dauphine would be good, but you dont really have those types of races at this point in the season.
