5:30am times are common practice around my southwest suburban schools. Especially this time of year when outside isn't an option. You typically have baseball, softball, badminton, tennis, wrestling, basketball, volleyball and soccer with some overlap right when spring sports/winter sports ends. Even with 3 court fieldhouses, it's impossible to get 3 levels of all sports in after school/evening. Especially if you don't have outside private facility use. Once weather breaks then it's all good. But every year we typically have that 2 week period where nobody is getting outside yet (maybe just soccer) and everyone else is left for indoor use. I know many schools try to make freshmen after school because they can't drive in the AM, but this is very very common and accepted in the 60423-60451-60448 area codes.
