The only explanation he attacedk at Pas de Payrol instead at the end of the stage if that he fears last week of Vingegaard and wanted more time in an stage that is supossed to suit him perfectly.
Poggi has a super attack, as Contador had, maybe better, and dont need an step climb for that. and as well he can hold that attack longer than Contador, who can get a good rent in 2 km, keep the rent 2 km more, bur start falling down later. But longer doesnt mean always, and Vingegaard has that resilience, he is going to keep the pace and going better and better with the Kms. In that is more similar to Froome, no so explosives riders, but if there si an attack they can go solo for a long time.
The problem for Vingegaard is to drop Pogacar. He has a good attack, but Pogacar is going to respond always if they are similar. He need to make the stage hard with his team (for Froome was the same) and to use the end of a long climb to insist with 2 or 3 attack and drop him. But once he drop him, Pogacar can lose minutes quite easy.
The rent is low, and Vin¡gegaard could put in the final ITT one minute if he finish well after the mountains, but there is a rent and he could try to support on his team mates as much as possible to defend, not to attack, and to use his powerfull attack to defend as well, and dont care too much of others riders.
He can try to allie with Remco if the situaction is good, and that is possible.
But anyway Pogacar said he trained especifically to longer climbs this year. We show him impressing at Catalunya and as well at the Giro, although no strong rivals, so I cant wait to see how he manage now in the high mountains...but anyway Vibgegaard is a point above than him....he has just Jorgesson for make it really hard, but maybe is enough.
