I just read an interesting article on japanrunningnews.blogspot.com about how a 15-year old in Japan ran 5:34.41 for 2k to break the 30-year old junior high national record.
Does the US even have a record like that? If so, what is it.
It equates to about a 4:23 mile.
The new record holder in the son of one of Japan's distance coaches.
Read all about it here:

Jr High Record? He's 15; that's Frosh/Soph Age.
USATF Junior Olympic "Intermediate" (15-16) is 8:27. Eric Hulst's 2mile record is 9:04. I would bet either of these gents and a few others could have held 4:23 pace for 5.5 laps.
I got the 4:23 mile mark from the McMillan calculator but LetsRun.com coaching genius John Kellogg has informed me that it really equates to something close to 4:20 in the mile.
And while I greatly respect Greg, no one knows more about running than John so let this stand as an official LetsRun.com correction.
Your a idiot

The school year in Japan starts in April, so ages and grades can line up a little differently than in the U.S. But, he is a 9th grader either way. That's junior high here.

2k is 5 laps.

both those guys are overstimating the mile time
it's worth ~ 4'25.1
using
ratio of speeds^0.0691729
for "equivalent power" in 1500 - M
empirical proof ?
sonia in '94 : 4'17.25 / 5'25.36wr
using that formula on 5'25.36 ->
~ 4'17.91
which is close enough...
Venty, this is one time I think you're slightly off. Even pace of 5:34.41 means one would come through 1600 at 4:27.53. So I think in order to do that and run another lap, you'd have to be able to run in the vicinity of 4:22 for 1600. Therefore, I think it is worth better than a 4:25 mile. I would even say it is probably worth 4:21 to 4:22 for a mile.
Chet
5'34.41 is 4'29.09 split for the mile
You have to ask whether a 4'25 guy can run 4'29 for the mile & hold on at that pace for another ~ 390m ?
The key here is that posters are showing too much bias towards shorter distance speed
We don't know if this kid's bias is towards the 1500 or to the 3k/5k
If his bias is towards 1500, then his mile equivalent woud be quicker than 4'25.1, if it's to 3k/5k, 4'25 woud actually be slow ( not by much though ! )
If he's "perfectly" unbiased between mile/3k/5k & 2000m, then 4'25 woud be the expected time
Tyr that formula on coupla notable runners :
komen : 3'29 - 3'30 for 3k & 5k
wang : 3'51.9 for 3k
between 1500 - 10k, 26'17.75 is 2nd best record out there ( better than 3k or 5k ) after the 1500
it is equivalent of 3'27.56
Yes, Venty, it would be partly predicated on the type of runner he is. Let's take a look at ElG. With 1500 of 3:26.00 and 2000 of 4:44.79, we have a ratio of .72334. This, if applied to the Japanese kid, would give him a 1500 time of 4:01.89. If we then use the 1.08 ratio, he'd have a mile time of 4:21.24. Just further food for thought.
Hicham's bias for 2k was obviously very strongly towards 1500 ( probably biggest understatement of the year )
( Also worth noting, he didn't have great splits for that 2k & was his only shot at it in his career - If he'd run it evenly or had a few goes that year, i think he'd have certainly got into the 4'43s )
I'd be surprised if this kid has that strong a bias towards the 1500 as japanese philosophy is towards huge mileage & i'd bet he's more 3k/5k biased than 1500, but you never know !
at one point last year I ran a 2k w/ splits of 68,67,67,67,62 5:33
when I started racing later that month i managed 8:30 , 4:20 and 1:58 in the span of 4 days.
Venty, with Lagat running 12:54 at age 35, and ElG having run 12:50, do you think that both of them, assuming they had focused on the 5000 in their primes, could have run low 12:40s? And since ElG ran 7:23, and Lagat ran 7:29 at age 35, don't you think they could have potentially been as good at 3000 meters as Daniel Komen? And I don't necessarily mean breaking his record, but Komen would have had a tough time beating them at 3000 if he couldn't break them before the finish, which wouldn't have been easy to do if they'd been in sub 12:45 shape.
I know, this attitude is so typical .... "15 years old is high school in the US so THEREFORE it MUST be high school everywhere else in the world."

Why don't you read the article? It says they focus on 400 m training and not mileage, and that he was national JHS 1500 m champ this year.

The article doesn't say that. It say that they focus on 400m repeats. It says nothing about the cklind of mileage they are doing.

No one knows more about running? That's a bold statement.
Does anybody have an actual answer to the actual question--what is the US Jr. High record?
Let's do that instead of focusing on arguing w/ Ventolin about the conversion to a mile. Pointless, the kid didn't run a mile, he ran a 2000. If you want to know what he can run in a mile, wait until he runs a mile race.
