17 racing days is pretty good for the Nations Cup circuit plus the other .1U and .2U UCI races on the calendar. If you add up the Nations Cup and the other U23 races, there are 60 racing days just for U23 racers. Not too shabby plus all of the other .2 and amateur racing that most teams take part in through the season. Yet without an overall season competition for all of the U23 races, it seems to be a bit...hollow. Even the Nations Cup is a bit hollow as trade teams are not involved. Imagine a competition with Colpack, Zalf, Axeon, AWT-Greenway, BMC Development, Lotto-Belisol U23 and a bevy of other amateur and continental teams.
