In almost every race yes, but for the Tour of Switzerland, there is no official classification for young riders so you have to send the top8 of general classification, points classification, king of mountains classification and team classification.

It is just that it might get confusing if a rider is the best young rider at Paris-Nice but three month later is not "young" anymore for the Dauphiné. So when you are young you stay young all year so it is easier to follow for the audience (but it is a totally artificial rule).
