That's odd. Last weekend the junior field was like 25 people total including the little tykes.
I'm trying to decide if I want to do both races next week or not. Last week in Cat5 I stayed with the group for two laps and then couldn't handle it anymore. Everyone gunned it out of corners and I can only lay down power like that standing - not something I wanted to do with the squirrel-y guys in the second group.
So, I just waited for the groups to come back around and I'd jump in the get some good group time for a couple laps and then die again.
PS: Don't get me started on the juniors riding S-Works frames and Cervelos.
