Would it be possible and legal to practice one or a few days a week at a different school's pole vault facility if their coach had asked me to come? I feel that I could learn a lot more there than at my school at the moment. I know that other kids from different schools practice there, but according to my head coach and pole vault coach, I'm not allowed to.

Is it okay? Is it legal? Or is my headcoach and pole vault coach trying to keep me practicing at their school.
THanks for your imput guys and gals.
