As Liss mentioned - minis race Saturday, but the Novice class races on Sunday. So your son could race the minis on Saturday and Novice class on Sunday.

However, one thing to consider is that you would be racing at the same time as your son on Sunday as both the +38 Int and Novice class go off in Race #6 (last race of the day).
