With the calendar rolling over to October, only a few short weeks remain in the 2024 regular season.

That means league titles will start to be decided very soon. Some marquee matchups await this month, as teams do their best to pull away from the pack. Less than 10 teams around the state remain undefeated, and that number could drop in the coming week.

Here is a quick overview of the state’s five classifications going into October:

Class 5A
