Donovan's season has bern plagued by injuries and bad luck.
Pidcock should be one of tge favourites. The route with rather easy mountain stages could also suit guys with a big engine who are good climbers, but not the best.
I thought Stewart broke his collarbone in Alsace? That's a very fast two week recovery... If he is racing here, I'd not imagine he'll get a chance in the sprints, probably works early for the Hayter-Pidcock-Bostock trio in the various finishes that suit each.
While Valle d'Aosta was a clusterfuck, he was the strongest in the race, maybe with a few others like Inkelaar and Hailu. He was in a different league in that Pyrénéen race. He's good, but i rate Van Wilder higher overall as GC rider, but he's younger.
