Etir Breaks Marugame CR, Catrofe Sets Uruguay NR, Omare 3rd-Straight Win




On the one hand it was too windy for really fast times at the Marugame Half, but on the other it wasn't, apparently.

It was pretty much a strong tailwind over the first 10 km and just a strong a headwind over the last 10, so it wasn't a surprise that the lead group of men went through 5 km in 13:59 and 10 km in 27:51. Up front in it were 59:30 collegiate record co-holders Richard Etir and Kotaro Shinohara, and sub-59:30 guy Emmanuel Maru. But with the National University Half Marathon having moved to Marugame last year there were a million fast Hakone kids up in it to, Hiromichi Nonaka from Koku Gakuin University leading the way but lots more right behind.

Etir and Maru opened up on the field after the turnaround, and by 15 km Etir was alone, 9 seconds ahead of Maru and on sub-59 pace running into the wind. Like everyone else he struggled to keep pace in the wind, sub-59 slipping away but easily taking the win in 59:07, a CR and new collegiate record by 23 seconds. Maru ended up almost a minute back in 2nd in 1:00:06. Uruguay's Santiago Catrofe won a sprint finish against Tomoya Ogikubo to set a new NR of 1:00:21 for 3rd, with Ogikubo tying all-time Japanese #8 in 1:00:22 for 4th and top Japanese.

4th and 5th placers Yuma Nishizawa and Neo Namiki both cleared 1:00:30, and Daisuke Sato of Chuo University made up a 10-second gap at 10 km to take the top Japanese collegiate spot at 7th overall in a PB of 1:00:40. The top 20 all broke 61, 11 of them collegiate runners, and excluding 2 people debuting, everyone in the top 25 except Maru and Norway's Sondre Moen ran a PB. A sub-61 half just isn't what it used to be. But the depth was as stellar as you'd expect from a top-tier Japanese half even with the wind, the top 70 going under 62 and 130 under 63. Down in 150th place, Tokyo Paralympic Yuki Iwata set a 1:03:12 WR in the ID class.






It was a pretty strong contrast in the women's race, where despite having men around to run with only 3 people in the top 20 ran PBs. 2-time champ Dolphine Omare went out in an aggressive 15:26 and 30:47 through 5 km and 10 km, 1:04:57 pace, but slowed as soon as she went around the turnaround and into the wind. She ultimately missed her own CR from last year by 10 seconds but still took 1st in 1:06:15, her 3rd-straight Marugame title. "She was OK through 20 km, but she really had a hard time in the last km," Omare's coach Stephen Mayaka told JRN post-race. "In better weather she can do 65 for sure."

Saying pre-race that she hoped to run 65, Eilish McColgan went out in 15:34 and 31:18, 1:06:02 pace, but faded even harder than Omare over the next 5 km. But where Omare continued to slow McColgan rallied, faster than Omare by 1 second from 15 to 20 km and by 3 seconds over the last 1.0975. "It was hard," she told JRN. "I was on my own a lot of the time. Men kept coming back to me, which gave me something to target, but they had all gone out too fast and were dying so I kept passing them. There wasn't anyone I could latch onto."

Japan-based Susan Kamotho ran an extremely well-paced debut, only 16:17 through 5 km but then clocking 16:00-16:03-16:02 to move pass Australian Isobel Batt-Doyle for 3rd in 1:07:56. Batt-Doyle hung on to 4th in 1:08:51, telling JRN, "I wanted to run better since I'd run well here before, but it was a hard day out there and I just told myself to make sure I got under 1:09." Tokyo World Championships marathoner Kana Kobayashi took the top Japanese spot at 5th in 1:09:28.

I understand the windy conditions made it tricky for the runners and for a proper evaluation but those are some very good times and every outing it's more and more encouraging for the half marathon guys in Japan.

Well done to Etir, well done to the top guys and have to say that Koku Gakuin will likely feel much better at the perspective or losing their 4th years when they have runners giving this kind of performance. Nonaka is a sure thing but having Takaishi debuting 1.00.53 as a first year is certainly encouraging. Does that give him the u20 NR for half marathon? Or is it a couple of months too late for that? I know Noda established the NR in november as a first year too so was wondering if Takaishi stole it or it doesn't count.

Chuo had very good performances too and I was surprised to see Yamamoto and Tamame from Juntendo running those times and improving that much. No idea how that program made that kind of progress over the last 12 months but it confirms the great result they had at Hakone one month ago.

The more we see these kind of performances from all these schools, the longer it makes the wait for the next Ekiden season.

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...

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...

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...
