It's also a physical issue. The training required to prepare for Paris-Roubaix is underestimated, especially for someone like him. Paris-Roubaix requires more training than competing in UAE Tour for 7 days, or even a harder one-week race.
It's oneday of competition, but it's backed by weeks of training and concentration.
Pogacar can win Volta Catalunya without being 100% shape while preparing for the Giro. According to what he said, he wasn't even 100% shape at the Giro to be able to 100% for the Tour. In contrast, in Paris-Roubaix, he had to be at 100% . He has to reach a 100% level tou Paris-Roubaix, take a break, and then be back at 100% for the Tour de France.
Last year was different; he was building his shape throughout the year until he reached 100% for the Tour. What he's done this year is more difficult, even though there have been less days of competition. We must forget about the days and analyze the intensity. Physically, this season has been tougher than last year because he had to be at 100% in the spring. Last year was a gradual growth period leading up to the Tour.
