Yeah Rojo-Ho-Hum...going back to the track is what it would take. As you say, Kawauchi-San has barely broken 14 in the 5k, and he would have to spend part of his year working on speed. Then his 10k would drop into the 27's and everything else would follow. You're right that 2:05 is a little too optimistic, but I think that 2:06 and 2:07 are doable, if he changes his approach, stops serial-marathoning, and focuses some on speed and quality. But he's apparently content to be media figure rather than the fastest Japanese marathoner. His 2:08:14 PR works out to somewhere around 27:40 for a 10k, if he got down to 27:40 and lowered it some more, his Half would come down a minute and the marathon would too. You say "so what" to a 2:06 or 2:07, but on some days, those kind of times can win a World Marathon Major, and it would be awesome if Kawauchi could do so, because he is an amazing competitor and character. I recall a pre-race photo from the Tokyo Marathon from a couple of years ago, with Kimetto, Gebrselassie, Kawauchi, and some other fast Japanese guys, all standing shoulder to shoulder with their fists held forward, in a sort of group point. The other fast Japanese guys smiled and looked sort of sheepish and silly, but Kawauchi glared at the camera like Toshiro Mifune in The Seven Samurai. And Kawauchi competes with a Mifune-like intensity, which is great. It would be fantastic to see him reach another level and win, something that won't happen unless he works on his speed and cuts the monthly marathoning.
