"Run one's course" is an expression that means to let something happen and finish naturally without interference from others. Ex: I think we should let the virus run its course. Ex: I know you don't like him dating your daughter, but you need to let this relationship run its course. She will realize he isn't good for her eventually. Ex: The flu usually takes about a week to run its course.
