Any good places to do some short distance sprinting in Cypress area?

I've been considering going back to some of the local high schools after school hours and sprinting on their tracks but I was told by a few friends that this might not be allowed regardless of the hours?

Kind of wondering if there are any public tracks that would be good for sprinting on.

I'm mostly looking for like the asphalt tracks / tracks that are marked so I can specifically tell the distance I can do my sprints for straight sprints and curves as well. Does anyone happen to do any sprinting here that has some advice for that?
