Kariuki Sets Okukuma Half Marathon Course Record

by Brett Larner

In a period that sees many of Japan's long-standing small elite races folding or changing to mass-participation formats the Okukuma Road Race, launched in 2013 in one of the most conservative areas of southern Japan, is something of a throwback, a small race of around 100 men with an accompanying high school boys' 10 km and women restricted to 5 km because, well, that's how they roll in Kumamoto.

In its third edition, Kyushu-based Kenyan John Kariuki (Daiichi Kogyo Univ.) led the top four at the Okukuma Half Marathon under last year's course record for the win in a new record of 1:03:16.  Essentially unchallenged, Kariuki had a lead of around 10 seconds at 10 km and held that margin to win by 13 seconds over London Olympics marathoner Ryo Yamamoto (SGH Group) with Shun Inoura, an alternate for Komazawa University's Hakone Ekiden runner-up team, another 3 seconds back in 1:03:32.

Still recovering from a sprained ankle a few weeks back, Asian Games marathon bronze medalist Yuki Kawauchi (Saitama Pref. Gov't) was 9th in 1:04:44 after running the early part of the race with Yamamoto.

Results were less noteworthy at the 39th edition of the Chiba Marine Half Marathon east of Tokyo.  Yuki Iwasaki (Sekino Reform) took a close men's race over Shota Yamada (Chiba T&F Assoc.) in 1:06:16 to 1:06:17, while Kyoko Koyama led a Juntendo University sweep of the top four places in the women's race in 1:18:40.  The best result in Chiba came in the women's 10 km, where Chiaki Morikawa (Starts) won in 34:28.

Kawauchi and Kiyara Headline Wan Jin Shi Marathon

Yuki Kawauchi (Saitama Pref. Gov't) returns to Taiwan's Wan Jin Shi Marathon this Sunday for his marathon of the post-Yuta Shitara era. The runner-up in Wan Jin Shi in 2016, Kawauchi is ranked #1 in the field and comes to Wan Jin Shi with wins in his last three marathons but faces a solid field including fellow sub-2:10 man Peter Kiplagat Sitenei, last year's runner-up Tsegaye Debele (Ethiopia), and the only man to beat him last time around, 2016 winner and course record holder William Chebon Chebor (Kenya). Kawauchi plans to use the hilly race as a tune-up for his main marathon of the spring season, April's Boston Marathon.

At the opposite end of the spectrum, Rael Kiyara Nguriatukei (Kenya), winner of the 2012 Hamburg Marathon before being stripped of her title and suspended for a positive post-race test for norandrosterone, has the fastest recent time in the women's field with a 2:26:22 winning time at last year's Chongqing Marathon. Close behind is Chemtai …

1500 m Olympian Assefa Wins Nagoya, 22-Year-Old Sekine 2:23:07 Debut

Two-time 1500 m Olympian Meskerem Assefa (Ethiopia) ran down favorite Valary Jemeli (Kenya) with 4 km to go to win the 2018 Nagoya Women's Marathon, with the home town crowd wowed by the debut of the latest next big thing, 22-year-old Hanami Sekine (Japan Post).

Supported by three pacers, a lead pack of seven including Assefa, Jemeli, Sekine, Ethiopian Bahraini Merima Mohamed, Saitama International Marathon winner Flomena Cheyech Daniel (Kenya) and top-ranked Japanese women Reia Iwade (Dome) and Rei Ohara (Tenmaya) went through halfway in a decent 1:11:32. This proved too hot for a few of the past next big things to have run well in Nagoya the last few years, as Sairi Maeda (Daihatsu), 2:22:48 in Nagoya three years ago, and Mao Kiyota (Suzuki Hamamatsu AC), 2:23:47 last year, were off the back of the pack in the first 10 km.

By 25 km Cheyech, Ohara and Iwade joined them off the back, leaving only Sekine in contention with the African trio of Jemeli, Assefa and Mohammed. Sekine, a…
