A good time i believe would probably have to be a 1:18:00 - 1:25:00... so a minute and 18 seconds to 1 minute and 25 seconds!! because there are so many 7th and 8th grade kids who run the 400m dash from 1:12:00 down to 55 seconds!!
A 400m dash is 0.4km.
Let's see.. For a 15 yr old boy a good 400m time would be 56-59 seconds. For a girl 64-66 seconds is better than average, 59-63 seconds is elite and anything that's 58 seconds and under is state material. For boys, state material is like 50 seconds and under. Hope that helps :)
It all depends on your age. If your in sixth grade, than: 31-33 If your in seventh grade, than: 28-30 If your in eighth grade, than: 26-28
1km = 1000m so the 1500m only
To train for the 400m dash you have to spend time on running long distances, and practise sprinting. because the 400m dsh is a bit if sprint, yet a bit of long distance. you will need to train for many years to win in the olympics. Probably about 10 or 15 years.
