New Japanese JR record for 100m... 10.01 seconds!

IAAF officially declines to ratify the 10.01 as a record:

He still has 1-1/2 year to break, he's still quite young. It's not first time the WJR is not ratified because of a wind gauge problem though...

Here he is running 10.17 in a high school meet this week:

The wind was legal, according to TV news reports.

Same 10.17, slightly different perspective. Turns out he ran it into a 0.2 m/s headwind:

No idea what kind of wind gauge was used, but it was a high-school meet.

Impressive sprinting by Kiryu.

He has such obvious weaknesses that when they are improved he will be excellent.

What are his primary weak spots? From what's been said about his training here its surprising he does so well late in the race and in the 200.

Also, any thoughts on the Danish kid?

Kiryu coming from behind for the relay win in the same meet last week:

40.65 seems like a pretty good time for a HS team, no? And the winning margin was only 0.04 seconds.

Thanks for the vid!

Inferior drive phase, lack of high-speed bloom because of forced transition.

He's powering it too much, blowing his wad too much in the first half.

It's youthful exuberance getting him to these times. Once that's gone, he will need to have some good form and race modeling to rely upon.

The Danish kid is no Kiryu, yet. While impressive, his exploits are still not significant, but they could be soon.

10.01 at 17 is VERY significant.

Speaking of which, Gemili is improving as expected, at 10.0x with a slightly illegal wind this past weekend.

I wish Kiryu would get more international exposure at this young age, to condition him to the variables of international competition, so that he doesn't need all those cues around him upon which he has come to rely.

Kiryu wins high school champs 200m in20.66 into -1.5 wind

Also before that (July 31st I think) he one the 100m in 10.19 (+1.9)

he may run the 4x400m too?

Good post. You see him leaning..about 10 meters to soon. Kid has alot to learn. He needs top sprint coach on the planet.

He will be in Moscow in the 100 and 4x100, but not in the 200

Re Radcliffe: one issue here may be the meaningless concept of a "world record" for the Marathon. There can only be a "best recorded time", which is how Marathon times were referred to in the more sensible past.

Here's what he was doing 5 minutes before the race as a warmup: http://www.youtube.com/watch?v=gEmJ-VWPDM4

Amazing how polite Japanese crowds are. Here in America several damn idiots would be jumping up screaming at the top of their lungs "Oooh boyz, he's kick yo ass. All of yo asses. There goes my n!gga, that's my n!gga. Yeah eat that ya'll"

Flo'da boy.... Haven't seen you posting in a while! Welcome back!

Good to see him running in top form again. I'd love to see him drop a tenth and become another potential contender for bronze.
