What is the fastest 400 M time you've seen personally in a High School Meet?

I saw a guy run like a 49 or something

About 49 seconds at an Invitational.

I saw Ted Ginn Jr. a couple of years ago when he was in high school set the Ohio state record...i'm pretty sure it was 48, 49 seconds. sub-50 anyway. turns out he was pretty fast.

ran against a guy that ran a 49. It really sucked finishing 25 meters or so behind him with a 52...

Two guys from the same team we were facing ran sub-50. Our top guy was sorta close with 51, but he was a freshman!!! so he will be a lot faster this year.

Being in Texas and working track meets for years, I have seen several 46s. It is not that uncommon to see 47.

at state a sophmore runner was around 49, he could do that early in the season too, so it's not really that great.

I saw this guy from Cahokia run a 47.50

about 48 seconds, he was f-l-y-i-n-g!

well... im only in middle school and we had a meet yesterday.... one of my friends ran like a 40.2- that was his personal best too
