it's true that there is a level of overwork/underfueling that can put anybody at risk of RED-S. (This number is different for everybody, and yes there are reasons why women are more at risk).
To answer the question you asked: no, a 2-3 mile run before a workout is not inherently bad for women.
To answer the question you didn't ask: I'd seriously consider whether there was something about me that made this athlete feel concerned. Imagine there is somebody at your box who is seriously underfueling, but insists they're fine. What would you expect to notice about that person (appearance, behavior, etc)? Do you share any of those traits? Is there any chance you might have an issue with health or fueling?
saying that I’m doing too much and that women’s body can’t do that much work unless they’re fueling properly and that I’m at risk of RED-s
