Racewalking isn't a bad thing! I used to do it competitively when I was too injured to run - this was about in Jr. High so I started young with the injuries. In nationals, I racewalked a 6 min 26 second mile. It takes a bit to get the style down but once you do, it's a lot of fun.

Now, I hope your friends/neighbors/loved ones are nice to you about it. It can be goofy looking.

I hope you get all of this sorted out with no permanent injury. I can't believe your coach. Sometimes they forget what it's like, I think.
