Karemi and Matsuda Break Okukuma Course Record - Weekend Half Marathon Roundup

For the second year in a row Japan-based Kenyan Jeremiah Thuku Karemi (Toyota Kyushu) broke the course record at Kumamoto's Okukuma Half Marathon. Coached by 1992 Barcelona Olympics marathon silver medalist Koichi Morishita, Karemi took 27 seconds off his winning time last year to win by over a minute in 1:01:21. Joel Mwaura (Kurosaki Harima) was a distant 2nd in 1:02:40, with Karemi's teammate Yuki Oshikawa (Toyota Kyushu) taking the top Japanese spot at 3rd in 1:03:13. Yuki Kawauchi (Saitama Pref. Gov't) was 9th in 1:04:04 a week after running the Ibusuki Nanohana Marathon.

In the women's race, Anna Matsuda (Kyocera), coached by former men's half  marathon national record holder Atsushi Sato, took 26 seconds off the course record to win in 1:13:10. Not far off, Kotomi Tsubokura (Wacoal) was a clear 2nd in 1:03:27 with Maki Saito (Higo Ginko) improving on her 10th-place finish last year to take 3rd in 1:14:46.

Also Sunday, up in Tokyo the Akabane Half Marathon celebrated its tenth running with a new men's course record. Yuki Kuroda (Comody Iida) became the first man to break 64 minutes on the Akabane course as he led the top three under the old course record set last year to win in 1:03:33. Last year's women's winner Tomomi Sawahata (Sawahatters) won again, 10 seconds off her 2018 mark in 1:15:12.

Nat'l University Ekiden Updates Here

Looks like I just went over my update limit on Twitter - sorry, it's the first time I've tried to use it for this. I'll look for another option next time. In the meantime I'll add updates to the comments below. Not sure if that has a max too but I guess we'll find out. Update: Part one of the Nationals commentary can be found here .

Top 7 Break NR at Ginza Road Mile

The mile isn't really a thing in Japan, especially on the roads, but it's starting to change a little bit. At Nike's new Ginza Mile road race, even in the middle of heavy rain the top 7 in the men's race all broke the national record of 4:00.02 set in March by Ojiro Honda (Waseda Univ.). Soma Nagahara (Juntendo Univ.) was first across the line to become the official new NR holder in 3:57.0, just beating Shunsuke Kuwata (Komazawa Univ.) by 0.3 in Kuwata's best race since the NYC Half in March. Kaisei Okada (Chuo Univ.) and Yuto Miyake (Chuo Univ.) were right behind in 3:57.9 and 3:58.1, and while there doesn't seem to be an official Taiwanese road mile NR it's pretty much a given that the 3:58.9 by Chien Tzu-Chieh (Chuo Univ.) for 5th was Taiwan's best-ever. Women's NR holder Nozomi Tanaka (Toyota Jidoshokki) easily won in 4:33.8, almost 2 seconds off her NR from 2023, with Wakana Kabasawa (Mitsui Sumitomo Kaijo) 2nd in 4:36.87 and Ran Urabe ...
