Muritu Over Fujimoto At Record-Breaking Kosa 10-Miler


Fukuoka wasn't the only big race in Japan yesterday. Just south near Kumamoto, the world's #1 10-miler took place in rural Kosa. Primarily a tuneup for the New Year Ekiden corporate men's national championships, the Kumamoto Kosa 10-Mile Road Race produced two of the fastest Japanese times ever, two national records, and record-setting depth.

Up front, a larger-than-usual contingent of Japan-based Kenyans and top-level Japanese talent including Chicago 2:07:57 man Taku Fujimoto (Toyota), Jakarta Asian Games steeplechase bronze medalist Kazuya Shiojiri (Juntendo Univ.) and others pushed through a 14:10 first 5 km despite warm and humid conditions and a light headwind. The lead pack gradually whittled down to five by 15 km, where John Muritu (Toyota Kyushu), Fujimoto and Cyrus Kingori (SGH Group) attacked at the base of a short downhill.

In the last sprint Muritu got away to take 1st in 45:56, with Fujimoto next in 45:57 and Kingori 3rd in 45:58. Fujimoto's time was one second better than last year's winning time by half marathon national record holder Yuta Shitara (Honda) and landed him at all-time Japanese #4. Following his 10000 m PB last weekend in Hachioji it looks like Fujimoto, a teammate of Fukuoka winner Yuma Hattori (Toyota), has recovered well from his surprise sub-2:08 in Chicago.

Shiojiri and three-time Kosa winner Jeremiah Thuku Karemi (Toyota Kyushu) were left behind by the top three's final attack, Karemi taking 4th and Shiojiri 5th in 46:06 to position himself as all-time Japanese #10. Veteran 2:07 marathoner and former Hakone Ekiden uphill king Masato Imai (Toyota Kyushu) had a surprisingly good day, taking 13 seconds off his 11-year-old PB for 9th in 46:22.


Wrapping up a three-week stint in Japan that saw him run a national record at the Ageo City Half Marathon and a 10000 m season best for the win at the Heisei Kokusai University Time Trials, David Nilsson (Sweden) ran in the second pack in hopes of breaking the relatively soft 48:34 national record. As in Ageo running without a watch, Nilsson found himself pulled along through a 14:13 first 5 km and 28:59 split at 10 km. Working together with 2015 3rd-placer Keijiro Mogi (Asahi Kasei), Nilsson pushed through the second half to take almost a minute and a half off the Swedish national record for 22nd in 47:10. Nilsson will compete for Sweden at next weekend's European Cross Country Championships.

Mongolian half marathon and marathon national record holder Ser-Od Bat-Ochir (NTN) also set a new national record, running 47:59 for 57th. Kosa this year broke the world records for depth set at the 2015 edition, with 92 men breaking 49 minutes and 114 going under 50. The next three deepest 10-milers in the world this year, Japan's Karatsu 10-Miler, the U.S.A. 10-Mile Championships and the Netherlands' Dam-tot Damloop, had 44, 34 and 25 men under 50 minutes, totaling less than what happened in Kosa.

In the high school boys's 10 km, last year's winner Ryuto Igawa (Kyushu Gakuin H.S.) ran one second faster this time, 29:44, but finished a distant second to winner Simon Kimunge (Tokai Prep Fukuoka H.S.). 16-year-old Masaya Tsurukawa (Kyushu Gakuin H.S.) was 3rd in 29:50. 2016 winner Erika Ikeda (Higo Ginko) returned to the top of the women's 5 km, winning in 16:36 by one second over teammates Eri Sakamoto and Suzuna Takano.

Nagoya Women's Marathon Preview and Streaming (updated)

Japan's winter marathon season of 6 major races in 7-straight weekends wraps up Sunday with the world's largest women-only marathon, the Nagoya Women's Marathon . The weather is looking pretty good, 6˚ at the start rising to 10˚ by the finish and sunny skies, but a moderate 7 m/s NW wind means a headwind finish that might impact the potential for some fast times. Official streaming kicks off at 9:00 a.m. local time. Live results will be here . Sheila Chepkirui won last year in 2:20:40, breaking away from Sayaka Sato and Eunice Chebichii Chumba at 30 km and hanging on for the win. Sato negative split a 2:20:59 PB for 2nd, Chumba fading to 3rd in 2:21:36. All 3 are back this time, but they have pretty serious competition from Aynalem Desta , 2:17:37 in Amsterdam last fall, and Selly Chepyego Kaptich , 2:20:03 in Barcelona 2023. And of course, Japanese NR holder Honami Maeda . Maeda ran 2:18:59 at the Osaka International Women's Marathon in 2024 to make the Paris Oly...

Chepkirui Over Sato Again to Win 2nd-Straight Nagoya Women's Marathon, Chen Breaks Malaysian NR (updated)

This year's Nagoya Women's Marathon felt like a changing of the guard, with some the bigger domestic names over the last few years fading early and a lot of newer faces stepping up with quality debuts or second marathons. The front group was set to be paced for 2:20 flat with the 2nd group at 2:23:30 to hit the auto-qualifying time for the 2027 MGC Race, Japan's L.A. Olympics marathon trials race in Nagoya. Up front things went out OK, but after a 33:10 split at 10 km Ayuko Suzuki , 2:21:22 here 2 years ago, lost touch, ultimately finishing 23rd in 2:33:28. Windy conditions started to play with pacers' ability to keep things steady and the pace slowed majorly over the next 10 km, but even with a 34:05 second 10 km there were big-name casualties. 2024 Nagoya winner Yuka Ando was next to drop, ending up 17th in 2:30:32. NR holder Honami Maeda was next, followed quickly by Bahraini Kenyan Eunice Chumba and debuting Wakana Kabasawa . Maeda faded to 21st in 2:31:21, whil...

How it Happened

Ancient History I went to Wesleyan University, where the legend of four-time Boston Marathon champ and Wes alum Bill Rodgers hung heavy over the cross-country team. Inspired by Koichi Morishita and Young-Cho Hwang’s duel at the 1992 Barcelona Olympics I ran my first marathon in 1993, qualifying for Boston ’94 where Bill was kind enough to sign a star-struck 20-year-old me’s bib number at the expo. Three years later I moved to Japan for grad school, and through a long string of coincidences I came across a teenaged kid named Yuki Kawauchi down at my neighborhood track. I never imagined he’d become what he is, but right from the start there was just something different about him. After his 2:08:37 breakthrough at the 2011 Tokyo Marathon he called me up and asked me to help him get into races abroad. He’d finished 3rd on the brutal downhill Sixth Stage at the Hakone Ekiden, and given how he’d run the hills in the last 6 km at Tokyo ’11 I thought he’d do well at Boston or New York. “I...
