Well, I suppose we can pencil in Ganna doing the Giro next year, but otherwise, it looks like the GC will be up for grabs at the Giro.
Jumbo, UAE, Bora & QS we can almost be certain of will have the A-team at the Tour,so we'll be left with EF (Carapaz?), Jayco (Yates?), Trek (Hart?) and if old man Thomas at Ineos can face living like a monk for 6 months he might do it again, I suppose. Otherwise the KOM & sprint competitions might well be the most intense. If Roglic and Pogacar get rolled over by Jumbo at the Tour, then the two of them will get most of Slovenia at the Giro if they do it in 2025.
That Jumbo send Kuss and the B-team, but still steam roller everyone else, must be a nightmare for the organizers, but the Giro really is in a squeeze next year with the Tour/Olympics.
