The difference was, that at the TDF, there were a lot of potential podium candidates that crashed or failed. In the Vuelta, it was basically just those 4 guys + Pogacar. Before the TDF, even Fuglsang was going to be a contender, Buchmann was going to surprise, Bardet was going for it... you name 'm. In the Vuelta, the candidates only had to watch 4 other guys. This is completely different in the TDF. You and your team have to respond to many more attacks, because there are many more candidates for GC. The entire TDF is raced a lot harder, average speed is usually a lot higher. There are more classics style stages, where contenders have to remain 100% focussed not to crash or get dropped on a cobbled section or by crosswinds. I can not understand that so many people on this forum do not see the vast difference between riding the TDF for GC and riding a Vuelta for GC. Even sprint stages are raced a lot harder in TDF in general, that GC guys have to remain very vigilant not to crash or lose time. There is so much more to it than gradients and number of climbs. But i'm not going to get suckered into this again after the Roglic topic. People who wish to remain oblivious, can be my guest. I'm nog going to go further into this again.
