Khishigsaikhan and Kuira Break Ageo City Half Marathon CRs (updated)


Stellar conditions and a solid fields meant times were going to be fast at the Ageo City Half Marathon, and in both the women's and men's races the front end took full advantage of the day. In the midst of the super-deep men's field Khishigsaikhan Galbadrakh, the top Mongolian in this summer's Budapest World Championships marathon and in last month's Hangzhou Asian Games marathon, ran steady and strong, splitting 33:29 at 10 km, 1:10:38 pace, before pushing the 2nd half. Khishigsaikhan crossed the finish line 1:10:32, 1:22 under the old course record, 3:35 ahead of 2nd-place Kana Kobayashi, and a massive 4:16 off the Mongolian women's national record. Khishigsaikhan is currently training in Japan and ran Ageo in prep for next month's Taipei City Marathon, where she was 3rd last year.




The men's race went out hard, with Kenyan Brian Kipyegon (Yamanashi Gakuin Univ.), NR holder Yusuke Ogura (Yakult) and the ambitious Rei Matsunaga (Hosei) leading the main pack out just over 60-minute pace. Sub-60 Marugame Half winner Paul Kuira (JR Higashi Nihon) pulled up next to Kipyego and together they started to edge away from the pack, which boiled down to around 15 behind them. Kuira and Kipyegon stayed side-by-side on track for around 1:00:50 until around 19 km when Kuira surged to drop the younger Kipyegon and sustained the attack all the way to the end.




Kuira broke the tape in 1:00:47, 30 seconds under last year's 1:01:17 CR. Kipyegon was next in 1:01:07, also under the CR. Behind him, Waseda University 2nd-year Tomonori Yamaguchi closed hard over the last 5 km to come rapidly back into range of the fading Kipyego. He came up 9 seconds short, but his 1:01:16 was also under last year's CR and took 31 seconds off 5000 m NR holder Suguru Osako's Waseda school record from the 2010 Ageo. Matsunaga held on for 3rd in a PB of 1:01:56, joining Yamaguchi in scoring invitations to next March's United Airline NYC Half in an ongoing program curated by JRN. The New York Road Runners' Sam Grotewold was on-hand to present the duo with their invitations at the post-race award ceremony.




Not far behind, Mongolian men's NR holder Ser-Od Bat-Ochir (Shin Nihon Jusetsu), now 42, improbably ran the 2nd-fastest time of his career, 1:02:37, to finish 14th overall in a tuneup for the Hofu Yomiuri Marathon in 2 weeks. En route he broke his own Mongolian road 5 km NR, splitting 14:23. "I loved the course," he told JRN post-race. "It had the perfect mix of flat and undulations. And so many fast guys! It was like getting on a shinkansen." After serial setbacks since a good run at last year's Oregon World Championships Ser-Od's hopes of becoming the first person to ever run 6 Olympic marathons look to still be alive.

And like always, the numbers just kept coming in. Ageo is ideally timed for the coaches of Hakone Ekiden-bound universities to run most of their rosters and thin down the numbers of contenders for their final Hakone lineups. Depth was incredible as always, even with direct conflict with the simultaneous 10-heat Kanto Region University 10000 m Time Trials meet going on at the Olympic Stadium in Tokyo:

sub-61: 1
sub-62: 4
sub-63: 26
sub-64: 66
sub-65: 119
sub-66: 179
sub-67: 215
sub-68: 276
sub-69: 321
sub-70: 362

Ageo's claim to the title of the world's deepest half marathon is still as strong as ever, even in the face of challenges from other Japanese races like the National University Half Marathon and Hakone Ekiden Qualifier Half Marathon.

Update: Australian Matthew Fox (Sweat Elite) was disqualified and given a lifetime ban from the Ageo City Half Marathon after running 1:06:54 with another runner's bib in the JAAF-registered men's division. The finisher totals above have been adjusted to reflect his DQ.

To the anonymous person who posted hourly identical demands for deeper results throughout the night while I was sleeping: That is a great way to ensure that I stop doing JRN altogether. I'm a person with a life outside JRN. I dedicate all of my available time and energy to JRN, and if I had the time and energy to post more you would see them. Relentlessly hounding me is only going to see me focus that time and energy somewhere else.

Japan Post Holds Off Sekisui Kagaku to Win Queens Ekiden National Title

  Japan Post  was back on top at the Queens Ekiden corporate women's national championships Sunday in Sendai, holding off last year's winner Sekisui Kagaku  over the second half of a race that came as close as 1 second to take 1st with a final margin of victory of 27 seconds. Sekisui Kagaku was out fast with a win on the 7.0 km opening leg by Erika Tanoura  and a new CR for the 12:56 second leg by Yuma Yamamoto , 17 seconds better than her own CR from last year. Last year's 4th-placer Shiseido  briefly led on the 10.6 km third leg with an excellent 33:17 stage win from Rino Goshima , but behind her Japan Post's Ririka Hironaka  returned from her latest injury problems to pass Sekisui Kagaku's Sayaka Sato  and hand off 6 seconds ahead. New recruit Caroline Kariba  ran Shiseido down on the 3.6 km fourth leg and put Japan Post 22 seconds ahead of Sekisui Kagaku, but a duel of marathoners between JP's  Ayuko Suzuki  and Sekisui's Hitomi Niiy...

Saku Chosei H.S. Makes It 2 In a Row - National High School Ekiden Boys' Race

While the girls' race was a blowout by 2022 champ Nagano Higashi H.S. , the boys' race at Sunday's National High School Ekiden was a tense battle of turnover that saw all of the final top four teams take a stab at leading. 2023 3rd-placer Yachiyo Shoin H.S. handled the first 2 of the 7 stages in the 42.195 km race, with lead runner Rui Suzuki delivering a bold run on the 10.0 km First Stage that produced the fastest-ever time by a Japanese runner on the stage, 28:43, and put Yachiyo Shoin 29 seconds out front. Last year's Fifth Stage CR breaker Tetsu Suzuki ran Yachiyo Shoin down to put 2023 champ Saku Chosei H.S. into 1st on the 8.1075 km Third Stage, but Genta Sugano of last year's 8th-placer Sendai Ikuei H.S. had other plans and took the lead on the 8.0875 km Fourth Stage. Smiling and fist pumping to the crowd almost the entire way, Taketo Tsukada of last year's 6th-placer Omuta H.S. moved up from 3rd to 1st by 2 seconds over Saku Chosei on the 3.0 k...

Nagano Higashi Girls Lead Start to Finish to Win National High School Ekiden

2022 National High School Ekiden girls' champion Nagano Higashi H.S. was back in force after a 5th-place finish last year, leading start to finish to win this year's national title Sunday in Kyoto. Lead runner Airi Mashiba kicked it off with a 19:30 stage win on the 6.0 km opening leg, something that head coach Fumio Yokouchi said later that he hadn't been expecting. That ended up being Nagano Higashi's only individual stage win in the 5-leg, 21.0975 km race, but the rest of its team ran well enough to hold a lead that was never less than 11 seconds but never more than 21. Last year's 4th-placer Kunei Joshi Gakuin H.S. spent most of the race in 2nd, but over the second half of the race Sendai Ikuei H.S. , 2nd last year by just 1 second, came from further back to run Kunei down on the anchor stage thanks in big part to a critical stage win on the 4th leg by Tsubomi Tezuka that put anchor Aoi Hosokawa in position to catch Kunei's Mizuki Oda . Nagano Higashi ...
