South Athletic Conference

Beginning with the 2025–26 school year, South High School is now a member of the new Glacier Trails Athletic Conference. With this change, South High will primarily compete within the new conference and no longer participate in the Fox River Classic Conference—except for football, which will remain in that league.

The Glacier Trails Athletic Conference includes seven member schools located on the northern edge of the Milwaukee metropolitan area:
Kettle Moraine Lutheran, Kewaskum, Plymouth, Port Washington, Sheboygan South, West Bend East, and West Bend West.
