Yes, but the alternative is what, hoping to be on a super day and make it over Mikuni with the best/lose as less time as possible and hope for no cooperation ahead.In these kind of hot and humid condition. going hard from far out can cost you. There's just no way to cool down anymore, in the same way as Strade bianche last year. Wout won there trying to keep his powder dry as long as possible.
I am looking at those results for people who can manage heat well, and i spotted Bettiol there doing a good result. He's my bet for an outsider to win here. But i wouldn't be surprised to see attackers on fuji cracking later and even if you do mikuni pass full gas from the bottom you can crack after that, it's still quite long to the finish.
I think I would take the bigger chance of blowing up and also a bigger chance of getting a medal than going for a safer top-10 option.
My prediction right now as that maybe something happens on the Fuji, but there will definitely be attempts in the 40k between Fuji and Mikuni.
