like mlb said, you might be good at the middle as well. I'd just try it. If it doesn't work out, that's just one meet that you wasted doing the wrong event. If you don't try and it turns out you were really good at it, that's a lot of meets wasted doing the wrong events.

I you were a natural sprinter, you would be doing the 100 (and the 50/60 meter indoors). And you would hate the 400. Pure sprinters tend to think of the 400 as a "long distance" event.

plus realize that most 400 runners in h.s. will move to the 800 in college....

There was a boy in the high school here who was State Champ in the indoor 55m (2001). In outdoor the track coach told him she would make him State Champ in the 400m. He did not want to run anything, but the 100 and the 200. He came in 4th, or 5th in the States, if I remember. He did not run the 400. Sometimes you listen to yourself. Sometimes you have to be "big" enough to realize that someone else might see you better than you see yourself. If you are not teachable (spelled c-o-a-c-h-a-b-l-e) you're toast!
Give it your best and you will learn something valuable about yourself.
