Some suggestions from an older internet rando:

Don’t dwell on the past, embrace it.

You worked your way up to a D3 runner, due 100% to your hard work, and despite the adversity of those who didn’t believe in you. Look back on that time as a challenge you overcame, and what brought you to the environment you are in today. Congratulations.

Consider telling your parents how you feel.

Right now, they are going around thinking that they pushed you hard, and that pushing is what got you where you are today. They are proud, of you for sure, but also of themselves as parents. Everyone, even your parents have the ability to learn where they were wrong, so consider opening up to them about how you appreciated their honestly, but their methods of delivering it hindered vs helped.

If you decide to do this, treat the conversation like your parents are the children, staying calm and informative, and you might be surprised how “adult” they treat you. And if they don’t, their loss.

Forgive, and move forward.

They did teach you to be reasonable, and try to remember it’s unlikely they meant purposeful harm. Regardless of if you discuss it with them, try to recognize it is your life now, and you get to choose how intactions go from here. Good luck in your races!
