Train really hard and start off medium and then start getting faster as 400m is not that far to run ALL RIGHT.
Bolt has run 45.28s for 400m.
Kignston summer 2012 400m in 45.86 secs
48 something
Try it and find out.
I don't know about the record, but I run the 400m for high school track. My PR is 63 seconds, but there are other girls on my 4 x 4 team who run 56's and they broke the school record. To get anywhere near a scholarship, you have to run at least a 57 for the 400m. It sounds easy but don't under estimate it until you try to run that time.
Alberto Juantereno from Cuba won the 400m and 800m at the Montreal Olympic Games in 1976.
Eric Liddell.
the total distance you run is 400m. so it is the same thing. all 4x100 means is that there are 4 people running 100 meters.
about 60 seconds.
I am not the best 400m runner. I ran 55 in high school, and the best could typically run it in 50. My track coach, who won 6 straight state titles, told me to run the first 200m at a near sprint. He said to run a 50, you want to run a 24 and a 26. He had us run a lot of 300s, and some 150s too. I hope that helps.
