Nishiyama Runs World-Leading 2:07:47 CR to Win Debut at Beppu-Oita Marathon


A few years back the Beppu-Oita Mainichi Marathon reworked its course to try to minimize the headwinds for which it's famous. In its 70th running today that paid off more than ever before, with 25~30 kph winds from the northwest keeping things controlled in the first 10 km and then giving enough of a boost to the pace from there to 35 km to help put the top two under the course record of 2:08:01.

Straight into the wind over the first 10 km the race went out reasonably, 2:08:16 pace through 5 km and 2:08:37 pace through 10 km. But after rounding the 10 km turnaround and picking up the tailwind things got faster, a sub-15 split over the next 5 km taking the projected finish time to mid-2:07 and going down as far as 2:07:12 before the last pacers stepped off at 30 km.

At that point there were still over a dozen people left in the lead group, most of them debuting or doing a first serious marathon and only a few experienced athletes like #1-ranked Shuho Dairokuno (Asahi Kasei) and Hiroto Fujimagari (Toyota Kyushu) still in it. But instead of slowing down they took advantage of the last 5 km of tailwind left before the 35 km turnaround. A series of people, Dairokuno, Tetsuya Yoroizaka (Asahi Kasei), Riki Nakanishi (Toenec), and Fujimagari, threw in surges before the turnaround that kept things on sub-2:08 pace and killed off the competition one or two at a time.

At 35 km the debuting Kiyoshi Koga (Yasukawa Denki), the fastest half-marathoner in the field at 1:00:49, put in the race-making move into the wind, opening a gap that initially widened to about 10 seconds. Yoroizaka, a track specialist making his real marathon debut after two training run-effort races overseas, and first-timer Yusuke Nishiyama (Toyota), the next-fastest half marathoner at 1:00:55, worked together to close it, and just before 40 km they did.

All three hit 40 km in 2:01:06, on track for 2:07:45. They could have backed off and left it for a sprint on the track at the end, but within a few hundred meters Nishiyama attacked, dropping Koga in a second and edging away from Yoroizaka. Nishiyama ran alone the rest of the way to break the tape in a world-leading 2:07:47, 14 seconds below the old course record, 6 seconds under the JAAF's 2:07:53 standard for its Oregon World Championships squad, and just 5 seconds away from the debut marathon national record. Yoroizaka also made it under the old CR in 2:07:55, a PB by almost 17 minutes but missing the Oregon standard by 2 seconds. Koga faded after getting dropped and was caught by Fujimagari, who took 10 seconds off his best for 3rd in 2:08:20, Koga next in a quality 2:08:30 debut.

All four met the criteria for qualifying for the 2024 Olympic marathon trials, and joining then inside the ring were 5th and 6th-placers Naoki Aiba (Chudenko) and Riki Nakanishi (Toenec), Aiba in a nearly 30-minute PB of 2:08:44 and Nakanishi in a debut 2:08:51. Sub-62 half marathoner Akira Akasaki (Kyudenko) was the unlucky fastest man not to qualify for the trials, but for a debut marathon there was no shame in his 2:09:17 for 7th. Likewise for 8th-placer Takeru Yamaguchi (Nishitetsu), who debuted in 2:09:56. Experienced marathoners Shogo Kanezane (Chugoku Denryoku) and Dairokuno took 9th and 10th, Kanezane just missing sub-2:10 with a 2:10:02 PB and Dairokuno 3 minutes off his best in 2:10:11 but still bettering his time from December's Fukuoka International Marathon by over 3 minutes.

All told, as expected this was really a race about the new blood, with first-timers taking 5 of the top 8 spots and only one experienced marathoner, Fujimagari, making it into the top 8. And everyone in the top 10 who wasn't debuting ran a PB except Dairokuno. And in the men's blind marathon, Shinya Wada (Nagase Sangyo) took 5:42 off the T11 class world record with a 2:26:17 for the win. It's safe to say that the race management's decision to rework the course to have the middle 25 km with probable tailwinds while still being well inside record-legal standards finally paid off.

Women were almost entirely eliminated from the field two weeks before the race when the organizers limited it to people with sub-2:30 times, IPC runners, and locals in order to cope with the omicron situation. That left Tokyo Paralympics blind marathon gold medalist Misato Michishita (Mitsui Sumitomo Kaijo) in the top spot. Like in the men's marathon Michishita took advantage of having 25 km of nonstop tailwind to be more than a minute ahead of pace to break her own world record at the 35 km turnaround point. But while Nishiyama and the others were able to race each other through the headwind over the final 7 km, Michishita faded majorly, winning in 2:57:20 just over 3 minutes behind her WR. Local Noriko Uchida was the top open division woman in 3:02:26.

Despite tougher standards than for the 2020 Olympic trials, after just three qualifying races 11 Japanese men have already qualified for the 2024 trials by either running sub-2:08, making the top 3 and going sub-2:10, or making 4th-6th and going sub-2:09. With only qualifying race so far 6 women have made the grade, over half the total number who ran the 2020 trials. They say that if you set the bar higher the athletes will respond. So far so good. If Osaka, Tokyo and Nagoya happen expect those numbers to go way up.

Great race!
Nishiyama couldn't make a better debut actually. Same goes with the other top marathon debut guys, impressive.
This race shows there's still a solid foundation and improvements can be expected all over the field and that's great.

Gotta also say that Aoyama Gakuin University keeps being terrifying:
-new captain Taiki Miyasaka debuting at 2:12:09 was impressive especially after running a disappointing over 1:05 half marathon last month. -
-SAame goes for Shungo Yokota at 2:12:41 for his debut. Both of these guys were Hakone alternates, not even starters.
-Ryo Nishikubo, another alternate had a good debut at 2:15.

These guys had a way better debut than Hakone starter Tadayuki Iida. Don't know about Kotaro Kondo (Hakone 2nd stage runner this year)who was supposed to run but didn't see him in the results.

These results show once again that AGU has incredible depth and their long distance preparation is top notch when it comes to running in January/February.

Japan's Olympic Marathon Team Meets the Press

With renewed confidence, Japan's Olympic marathon team will face the total 438 m elevation difference hills of Paris this summer. The members of the women's and men's marathon teams for August's Paris Olympics appeared at a press conference in Tokyo on Mar. 25 in conjunction with the Japan Marathon Championship Series III (JMC) awards gala. Women's Olympic trials winner Yuka Suzuki (Daiichi Seimei) said she was riding a wave of motivation in the wake of the new women's national record. When she watched Honami Maeda (Tenmaya) set the record at January's Osaka International Women's Marathon on TV, Suzuki said she was, "absolutely stunned." Her coach Sachiko Yamashita told her afterward, "When someone breaks the NR, things change," and Suzuki found herself saying, "I want to take my shot." After training for a great run in Paris, she said, "I definitely want to break the NR in one of my marathons after that." Mao

Takeuchi Wins Niigata Half in Boston Tune-Up

Running in cold, windy and rainy conditions, Ryoma Takeuchi (ND Software) warmed up for April's Boston Marathon with a win at Wednesday's Niigata Half Marathon . Takeuchi sat behind Nittai University duo Susumu Yamazaki and Ryuga Ishikawa in the early stages, then made a series of pushes to pick up the pace. Each time he tucked in behind whoever went to the front, while behind them others dropped off. Before 15 km only Yamazaki and Riki Koike of Soka University were left, and when Takeuchi went to the front the last time after 15 km only Koike followed. By 16 he was gone too, leaving Takeuchi to solo it in to the win in 1:03:13 with a 17-second negative split. "This was my last fitness check before the Boston Marathon next month, and my time was right on-target," he said post-race. "Everything went as planned. I'm looking forward to racing some of the world's best in Boston, and my goal there is to place in the single digits." Just back from tr
