There’s two (or more) sides to every story and the truth is often in the middle. I’m only reading your view on a situation here and I’m wary that I don’t have the full picture while writing this comment.

Your parents remind me of the meme “you’re not wrong, you’re just an asshole”.

There’s ways to frame feedback - if you’re not achieving a standard set by a teammate who already isn’t qualifying for upper levels of competition, then it’s not a reason to knock the dream on the head, but a part of a training roadmap. If you’re banging in 29min 5ks or 5000m events (I’m making the assumption that’s the distance in mind here), then the plan would be to adjust training and diet to tag each of the minute barriers until you can clear 22min and top your team’s timesheets.

After that, you can look at what generally gets you a qualifying time for state or national competitions, and train for that. Once you’ve achieved that then you’re probably beyond what your parents or coach can help with and you’ll probably need elite or semi-pro level of coaching after that.

Negativity from your parents isn’t helpful though, and no not everyone does it. I don’t know whether it comes from a place of personal failure in your mother’s youth or whether she’s scared that you’re running into the unknown, but it isn’t helpful.

As for your dad though, I thought that it was kinda cool that he wanted to let your HS coach about how you’re getting on now. Everyone’s first crack at a distance event is awful, that’s how you develop - so it’s cool to be able to say to your old coach “hey that first 5k wasn’t spectacular, but check these times out now!”.

Either way, you’re running for yourself. If you train well, your times will come down, and you will start turning heads - whether your parents are supportive or not. One of the most important lessons I learned (and I’m nowhere near club level running let alone elite level) is to run your own race. It’s good for the mind, good for the soul, and helps you sleep at night.

Good luck, well done on what you’ve achieved so far, and hopefully the stopwatch will start giving you much better feedback than your parents.
