He doesn't have any good results in such long races, but he can do really well. He used the Vuelta as training.
He says he feels better than ever. In the Vuelta, he said he couldn't help better because he din´t feel well

. But we already saw that he won the stages and used the rest of the stages to train.
The Vuelta has always been considered a race that gets the rider in top shape for the World Championships, and Ayuso didn't do the Tour de France, and he didn't even do GC at the Vuelta.
I do think he's very strong. We'll see what it's good for.
