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.

Measuring Marathon Courses by Bicycle

http://news.searchina.ne.jp/disp.cgi?y=2013&d=0110&f=column_0110_034.shtml translated by Brett Larner The full marathon is a sport where you compete over 42.195 km, but how do they go about measuring that distance?  Today we're going to look a little bit at how they go about certifying the distance of a marathon. The reality is that major international marathons use a bicycle to measure the distance.  This rule is an international standard, and the same method of measurement is used everywhere.  It was put into place in 1986.  In order to ensure that the same method is used everywhere, a bicycle that meets IAAF specifications must be used for measurement. In the case of Japan's major marathons, to be certain that the distance is correct a provisional measurement is first made.  Before the course is certified using a bicycle the course is measured using a 50 m-long length of wire to determine that it is in fact 42.195 km.  When a bicycle is u...

Ai Hosoda Announces Retirement

photo © 2025 Victah Sailer/Photo Run, all rights reserved On Jan. 8 the Edion women's corporate team announced that Ai Hosoda , 30, will retire at the end of March this year. The Tokyo Marathon will be her last race. At Nagano Higashi H.S. Hosoda ran in the National High School Ekiden her 2nd and 3rd years. During her 3rd year at Nittai University she won both the 5000 m and 10000 m at the Kanto Region University Track and Field Championships, going on to win the bronze medal in the 10000 m at the World University Games in her 4th year at Nittai. After graduating she joined the Daihatsu corporate team, debuting at the 2019 Nagoya Women's Marathon in 2:29:27. 2 years later she transferred to Edion. She qualified for the Paris Olympics marathon trials at the 2022 Nagoya Women's Marathon and finished 3rd in the trials in the fall of 2023, but was later bumped down to Olympic alternate after another athlete ran a faster time. Instead of the Olympics, Hosoda ran the 2024 Ber...
