It was so much fun seeing van der Poel and the others (including Charmig) exhaust everyone from so far out, but without the part where Pogacar wins and makes it boring.
As for the cramping, I think Del Toro and Seixas are just a little young, haven't done many classics style races against top opponents. And of course, 270 km races are very different from 220 km races. You can see how some riders - like Pedersen, van der Poel, McNulty - don't decline as fast as other people do when the race is so long.
Btw, someone needs to tell Seixas not to be so hard on himself, he's almost ready to jump from a building after not winning the WC at age 20. France rode a good race, Amirail was impressive, and Seixas will get stronger for the next 5-6 years at least. Chill out.
