ADHD medication and exercise

Hi everyone,

Tomorrow I am starting to take ADHD medication for the first time. I am planning on going to the gym and running for an hour before class. I normally eat after I work out.

Does anyone have a suggestion whether to take my Adderall before or after working out and before or after eating?
I forgot to ask my doctor and because he didn't mention it, I assume it isn't a huge deal.

Thanks
