10000 m National Championships Preview

Given all the breakthrough runs over 10000 m in Japan the last few weeks, enough to take Japan to 30 men sub-28 for the distance this year, it seems a bit odd to have the 10000 m National Championships happening this Sunday in Tokyo's National Stadium. But relative to the timing of ekiden season, the rest of the National Championships in the late spring, and next summer's Paris Olympics, it makes sense. NHKBS is broadcasting it live, with the men's race starting at 16:03 and the women's at 16:43.

The 27:00.00 would be a stretch at this point for any of the Japanese men in the race, but one woman, former 5000 m NR holder Ririka Hironaka (Japan Post) has actually cleared the 30:40.00 standard before with a 30:39.71 at the 2022 Oregon World Championships. But that was before the qualifying window opened, so she'll have to try to continue to build back from the injuries she suffered last winter if she wants to hit the standard here. Her best this year is 31:35.12 at the Budapest World Championships, so if she doesn't clear the standard, a win here and something closer to or under the standard sometime in the spring would be enough to get her to Paris

Hironaka's main competition at 31:22.38 is women-only half marathon NR holder Rino Goshima (Shiseido), who broke Hironaka's CR on the opening leg of the Queens Ekiden at the end of November. Tomoka Kimura (Sekisui Kagaku) is a little ways back in 31:56.32 after sitting the Queens Ekiden out. Goshima's Kenyan teammate Judy Jepngetich is there as a de facto pacer, with the addition this year of the Wavelight pacing system, the red lights up front set for 30:50 and the green second set for 31:10. Wakana Kabasawa (Mitsui Sumitomo Kaijo) is a dark horse coming in with a 15:19.98 best for 5000 m.

The men's race has a Kenyan pacer too, Sitonik Kiprono (Kurosaki Harima) the fastest in the race at 27:14.76. At 27:28.04 Ren Tazawa (Toyota) has dominated the distance domestically in the long absence of NR holder Akira Aizawa (Asahi Kasei), but Aizawa is back this time along with his catalyst for greatness, Tatsuhiko Ito (Honda). Kanta Shimizu (Subaru) is a threat for the win with a 27:31.27, and Tazawa's teammate Tomoki Ota (Toyota) rounds out the Japanese top 5 at 27:42.49. But with 16 Japanese men with sub-28 bests in the field it's likely to be another shinkansen-style race with some unpredictable results.

Many of the fastest Japanese men won't be there, having just dropped their big times in the last week or two. That includes Hakone Ekiden champ Komazawa University's Keita Sato, Mebuki Suzuki and Kotaro Shinohara, Jun Kasai (Asahi Kasei), 19-year old Sonata Nagashima (Asahi Kasei) and Chuo Gakuin University's Reishi Yoshida.

Australian YouTuber Handed Lifetime Ban by Ageo City Half Marathon After Running 1:06 with Another Runner's Bib (updated)

After discussion with their race's chief JAAF referee, on Nov. 27 the organizers of the Ageo City Half Marathon handed down a lifetime ban from their event against 36-year-old Australian Matt Inglis Fox for running the Nov. 15 race wearing the bib number of another JAAF-registered runner. The incident came to light after Fox posted on his personal Instagram account that he had run a PB of 1:06:33 and finished 203rd in Ageo with a 10 km split of 31:03, along with photos and video of himself in the race wearing a bib number beginning with 11. Fox did not appear in the results by name or in that time or place, the closest match being a 1:06:54 gross, 1:06:50 net finish time with a 31:21 10 km split for 18th place in the JAAF-registered division and 209th overall by bib number 1129, registered to a non-Japanese Tokyo-resident club runner. The club runner, Harrisson Uk , readily confirmed that he had given his bib to Fox, saying, "I gave my number to Matt. It wasn't me."...
