Yeah, but Pogi doesn't really care about winning multiple Dauphine.
Dauphine definitely isn't TdF, WC, a Monument... or Strade Bianche.
Its prestige, for someone who won multiple TdF, is pretty relative.
Who even cares?
Now, winning multiple RVV, as a GT guy, is something actually prestigious.
He stated in that past he'd like to win all of the 7 major 'one week stage races':
en.wikipedia.org
And even that isn't high on his list.
Anyway, in 2026 TdS will also only be 5 days, opposed to the usual 8 of Dauphine.
So pretty convenient.
Dauphine ending one week earlier might be a factor, but other than that, between the two, I don't how he'd pick Dauphine instead of TdS in 2026.
