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.

Kazami Breaks 100 km World Record at Lake Saroma

Running on the same course where Japan's Takahiro Sunada set the road 100 km world record of 6:13:33 twenty years ago, 2:17:23 marathoner Nao Kazamibested a deep and competitive field to win the Lake Saroma 100 km Ultramarathon in a world record 6:09:14.

Part of a front group of at least five that went through the marathon split in 2:33:36, on pace for 6:04:01, Kazami lost touch with the lead as rivals Koji Hayasaka and Takehiko Gyoba surged just before halfway to open a roughly 30 second lead that lasted until nearly 75 km. But in the last quarter of the race Kazami, a graduate of Hakone Ekiden powerhouse Komazawa University, was the only one who could sustain anything close to the early pace, overtaking Hayasaka and Gyoba before pulling away to open a lead of over 11 minutes. Kazami's mark took more than 4 minutes off the world record, and he also bettered the 100 km track world record of 6:10:20 set in 1978 well before he was born by the late Don Ritchie.

Tanaka and Hashioka Win Gold - World U20 Championships Day Two Japanese Results

Working together to execute an aggressive frontrunning team strategy born from failure two years ago in Bydgoszcz, 2018 Asian U20 3000 m gold medalist Nozomi Tanaka and 2018 Asian Junior Cross Country gold medalist Yuna Wada opened a massive lead over the African Junior Cross Country medalist Ethiopian duo of Meselu Berhe and Tsige Gebreselama in the early going of the Tampere World U20 Championships women's 3000 m. Tanaka took the lead from the gun before Wada went out front at 200 m to set a fast pace. Through splits of 3:00 and 3:03 for the first 2000 m, Tanaka kicked hard from 300 m out to close with a 2:51 for Japan's first-ever gold medal in the event, winning in a PB of 8:54.01.

Berhe and Gebreselama caught Wada on the back corner but weren't even close to matching Tanaka, taking 2nd and 3rd in PBs just under the 9-minute mark. Wada just held off Kenyan Jenali Jemutai Yego for 4th in 9:00.50, seeming happy in post-race interviews to have helped a teammate score gol…

Kamulu Runs 10000 m World Lead, Ahn Breaks Korean National Record, Tamura Clears 28 Minutes, Niiya Back on Track in Fukagawa

National records fell for the third meet in a row in the four-part Hokuren Distance Challenge series Wednesday in Fukagawa, Hokkaido. Longtime Japan resident Pauline Kamulu (Route Inn Hotels) had a shockingly good run in the women's 10000 m A-heat, following up her 1:06:56 bronze medal run at the Valencia World Half Marathon Championships by lopping over a minute off her 10000 m best with a 2018 world-leading time of 30:41.85.

Kamulu lapped the entire field, her nearest competitor Honami Maeda (Tenmaya) returning from a 2:23:46 marathon PB in Osaka in January to take 30 seconds off her own best in 32:13.87. Further back, Seul Ki Ahn broke the South Korean national record set 13 years ago in Fukagawa with a new mark of 32:33.61. Ahn's NR followed the 2:25:41 NR set by Do Yeon Kim at the Seoul International Marathon in March, a miniature renaissance in South Korea women's distance running.

The men's 10000 m A-heat was also decently fast, Andrew Lorot (Subaru) leading fo…
