hey, i just started running track this year as well
same age and everything
practicing always works, but running 100 meters over and over again isn't the right way i mean yeah do it a couple of times but not the whole time
try relaying and working on you're breathing when you run and feet positioning
oh and also just remember there's a lot of stuff you can do in track besides 100 m and since you're twelve you don't really have to be at your tip top level i mean i'm not that good this year but the reason im in track is because i'm building up for next year so i can blow the opponents away
i also agree with Peaches make sure you stretch and warm up
