For the people who know quite a lot about sports: wanting to go for a run but got an important medical exam tomorrow?

I have an important medical test tomorrow, to see if 'm physically fit for a certain job. They look at your height, weight, eyes, ears, heart, lungs, ... the whole lot.
Now I'm not the most sporty person out there, but I try to maintain my physique. I used to go for a run three times a week but the last few weeks I haven't had the time and had some other lame excuse. I started again last Sunday and went for a 5k without much trouble, I'm trying to keep this up and I wanted to go for a run today but my dad told me not to since I have this medical exam tomorrow.
Would it be bad for my heartrate or something if I went for my 5k run today while having that medical exam tomorrow?
