Beppu-Oita Mainichi Marathon Elite Field


The Feb. 1 Beppu-Oita Mainichi Marathon is coming in hot this year with what's got to be a shot at the 2:04:55 Japanese NR. Up front is the king of this year's Hakone Ekiden, collegiate marathon NR holder Asahi Kuroda of 2026 Hakone champ Aoyama Gakuin University. Last year at Beppu-Oita AGU's Hiroki Wakabayashi ran a 2:06:07 debut to break the collegiate marathon record. 3 weeks later Kuroda bettered that with a 2:06:05 in his debut in Osaka. He comes in fresh off the greatest run in Hakone history, taking 2 minutes off Wakabayashi's CR for the massive uphill Fifth Stage in a run that Letsrun.com estimated was worth a 57:30-58:00 half marathon. Make of that what you will, if you accept 58:00 that's worth sub-2:02 in the marathon. Call it 59:00 and you're still talking sub-2:04. Can he possibly live up to the hype?

Beppu-Oita is basically not that kind of race, but looking at the rest of the front end of the field they've got to be thinking that way. 2:04:22 Kenyan Ronald Korir, Fukuoka International Marathon CR holder at 2:05:16 and AGU grad Yuya Yoshida, and multiple 2:06 runner, even pre-carbon shoes, Hiroto Inoue. Add the cream of the debuting people, sub-61 half marathoners Toru Kubota and Daiki Hattori, and 3 other members of AGU's 2026 Hakone roster, Shota Shiode, Kyosuke Hiramatsu and Shunya Udagawa, and it's going to be great.

There are a ton of others in the 2:06 to 2:09 range and debuting off 61-minute half marathons or 27-minute 10000 m times, and they'll pretty much all be going for qualification for the L.A. Olympic marathon trials to be held in the fall of 2027, because it's never too early to obsess over that. Basically they have to be in the top 6 Japanese finishers and sub-2:09:00, or sub-2:06:30. A 2:03:59 would let them bypass the trials altogether and score a place on the L.A. team, assuming nobody else beats their time before then. That wouldn't have seemed realistic pre-Hakone, but what's stopping Kuroda here? Gravity didn't at Hakone.

What a great marathon this could turn out to be. Deep and with interesting field and debuts in addition to Kuroda.

Not sure if the translation was accurate but I think I read Hara advising Kuroda to aim for the 2.03.59 in Berlin (would check with Ota running Berlin after graduating too). Maybe he'll use Beppu like Brett suggested to qualify for MGC and aim for Berlin in September but NR could be on the cards right away if he hasn't had issues after Hakone. Safe to say it should be a great run.

Curious to see what the pacers and target time look like.

I'm sure it'll end up being something more like 2:05-06 here, but it'll be exciting either way. Hirabayashi had a hard time repeating his debut, but Kuroda doesn't seem to miss.

2:05/06 sounds reasonable, i think Kuroda has an higher ceiling than wakabayashi/hirabayashi but its a marathon so we will see how it goes and it ll be a long season.

Ayaka Suzuki, Younger Sister of Olympic Marathoner Yuka Suzuki, Faces Final East Japan Women's Ekiden

The final edition of the East Japan Women's Ekiden takes place Nov. 10. 18 teams representing the eastern prefectures will bring high-level women's competition to the streets of Fukushima. Getting attention on the Akita team is Ayaka Suzuki , the younger sister of Paris Olympics marathon 6th-placer Yuka Suzuki . Ayaka is a 3rd-year at Akita's Omagari H.S. She began running seriously after entering high school, citing her sister's influence. "When I saw her winning her stages and helping her team in university ekidens, I thought that I might be able to do the same and decided to give it a try," she said. Before her excellent run at the Paris Olympics Yuka ran the East Japan Women's Ekiden 3 times, inspiring others as she went from a young athlete to one of the best in the world. "I was surprised that she was competitive at that level," said Ayaka. "When I saw how strong she was running it really moved me." In junior high school Ayaka w...

Aoyama Gakuin Breaks Hakone Ekiden CR for Second Year in a Row

2024 Hakone Ekiden course record breaker Aoyama Gakuin University was 3:16 up on 2023 winner Komazawa University at the end of Day One of the Hakone 2025, an even bigger margin than last year when it was 2:38 ahead of Komazawa and went on to win the 217.1 km overall race in a course record 10:41:25, beating Komazawa by almost 7 minutes. There was almost no chance Komazawa could close the gap today on the return trip of Hakone Day Two. But that doesn't mean they didn't try. Komazawa 3rd year Aoi Ito was just off the CR on the ~800 m downhill 6th leg in 57:38, but even with a run that good he lost ground when AGU's Akimu Nomura proved a hypothetical, breaking the 57-minute barrier for the 20.8 km leg with a 30-second CR of 56:47. Post-race Nomura said that he had spent the whole year training to run 56, and he executed perfectly. And put AGU 4:07 ahead, hopeless, except for a ray of hope. Injured for most of 2024 and running his first race since March on only 6 weeks of...
