Anecdotal but about 90 percent of the joggers I see are female.
I think I would agree with that as well, anecdotally, there do appear to be far more female joggers...but when it comes to strength, women can exercise to the pinnacle of what is achievable for them (as some female athletes do) but when they stop exercising, they lose that strength at a faster rate than men do.
Men have a higher base, and due to testosterone, lose it slower. An unfair natural advantage, if you will.
