if it's a bacterial based cough you won't be running at all - you'll feel shit and be hacking up loads of phlegm and probably on antibiotics.
what you probably have is a viral cough which can persist and wll eventually go away - it can't be treated with antibiotics. it's the sort of cough that annoys you and everyone else around you. all you can do is try to stop the cough.
get some Pholcodine cough liquid from the chemists - it reduces the cough reflex - that helped me when I had what you describe at the start of the year
and I suspect you will be fine for Sunday
