Class History
The IESA sanctioned Cross-Country in 1979. There was one class of Cross-Country until 1997 when the activity was split into A and AA based upon enrollment. It was split in 2012 into three classes of 1A, 2A and 3A. In 2023 it was split again into the current four classes of 1A, 2A, 3A and 4A.
