What can a muslim girl wear in gym class and still be hijab?

Asalamalaikum! I recently converted to Islam and I'm still learning the correct and incorrect ways to wear hijab. But, I have to take a gym class while I am at college, and for one of my classes, Pilates, my hijabi is fine because it is indoor. But my second class is PE and we are sometimes outside running in 80-90 degree weather and it's too hot. Would it be okay if i wore those long basketball shorts that go down past the knee, and leggings underneath? i am still covering everything. I wear a long sleeve shirt and teeshirt overtop which is fine, but its just the bottom that makes me want to pass out.
