Friday Open Thread: Have you tried changing your running form? Did it work?

So I’m trying something new today, an open thread with a question/topic to which you can reply. One of the biggest questions I have is, I’ve been to many different panels and demonstrations of different ways to change running form. But I’m wondering, have any of you ever tried it, and has making those changes delivered long-lasting results for you? Sincerely interested to hear your thoughts. — Terrell
