Kongsberger Ski Club uses the following age classes for our races.
Your age group is determined by your age as of December 31 of the competition season.
You race in the same age group for the entire season.
Beginning with 2013-2014 ski season, USSA has adopted the "U" age class system
with "U" or "Under" replacing the "J" system for junior age groups.
OJs are now U20s, J1s are U18s, J2s are U16s, and so on.
