Whats a good 400m time for a 15 year old?

Question

I used to be a 1500 m runner and i got a best time of 4:39, but i didnt enjoy it much. Im thinking about trying out the 400m. I tried it once and got 56 seconds. Is this good and what should i do in training to make it better?

Answer 1

 d**n i feel like a fat a*s now i ran a 1:02 today

Answer 2

Freshmen year i ran a 54.56, didn't do it sophomore year, track started yesterday ran a 57 without training, the record is 49.02 1996, its mine. 15 year olds should be running around 56. im just gifted [: i go to foothill high. i can prove it there. i WILL be knocking on the door to the olympics.
