My dad would be that guy, but he’s a running coach and was a marathon runner for like 50 years, so he loves talking about it.
There definitely wouldn’t be any thought of, “you’re a woman so you need advice,” since he’d do the same thing to a man.
In fact, if we actually accept this completely unbelievable story, the fact that he’s pulling stats from Women runners shows he’s not being sexist.
Your dad sounds like an asshole and id avoid bringing up running. I’d enjoy talking about it. But I wouldn’t want a teaching lesson from someone who has, as far as I know, no credentials or authority on the topic because, if we assume it’s like the post, none were given. Plus I’d rather they find out my level of knowledge before they assume I know nothing. Basic respect. Your dad has none. And you don’t either.
Edit: most running plans aren’t gendered so he may not even know it’s from a woman. Many plans get shared, gasp, through social media and credit can be lost. You’re actually fucking awful at drawing logical conclusions. Take a college course in logic once you reach there as I can’t imagine you’re that old or experienced with your approach to communications.
