Hokkaido Marathon Elite Field


The Hokkaido Marathon happens Aug. 30 in Sapporo. Although it's not a top-tier race on the global schedule, the JAAF gives it special status in qualification for the MGC Race Los Angeles Olympics marathon trials, with 3 spots available to men who run under 2:12:00 and women under 2:32:00. Compare that to the criteria for making the trials by running the WA platinum label Sydney Marathon the same day, where men have to run under 2:06:30 and women 2:23:30 regardless of how they place. It's hard to see that as anything other than disincentivizing Japanese runners from racing abroad, with protecting the JAAF's financial interest in domestic races being the priority over getting the best athletes into the Olympic trials.

But anyway, there are pretty good fields of people willing to not step out of line. All 6 women with marathon finishes to their name have run under 2:30 in the last 3 years led by veteran Hitomi Niiya with a 2:21:50 in Tokyo 2 years ago. Most are in the 2:26-27 range, giving them a decent margin of comfort under the 2:32:00 trials standard even though Hokkaido tends to be warmer than ideal. 3 good newcomers join them too, with Amisa Murayama having run the first 30 km of January's Osaka Women's Marathon in 1:41:43 before stopping as planned, Shiori Yoshizono with a 1:08:21 half best, and collegiate 10000 m record holder Seira Fuwa making an early debut. Tokyo Olympics 5000 m runner Kaede Hagitani will also debut.

Simon Kariuki is the fastest man in the field with a 2:06:29 best, but of course he doesn't count in trials qualification. Yuta Koyama and Masato Arao are the fastest current Japanese men in the field, Koyama in 2:07:25 in Osaka this year and Arao with a 2:07:42 for 6th in Sydney last year, a performance worth at least a 2:05 on a flat course. Arao is recovering from an injury in the spring and looked good pacing the Gold Coast Marathon this past weekend, but there is a lot of competition at the 2:08-09 level and top 3 won't be easy for anyone. Throw in Osaka Marathon front-running wildman Hibiki Yoshida, who has hopefully worked out the fueling issues that cost him a massive performance in Osaka, and it's hard to pick who will fill out the 3 spots in the trials field.

Just from analyzing the records from 2022 to 2025, the race temperature should be above 20 degrees making for a slow race. Results have indicated this with the fastest female winner in this period being Haruka Yamaguchi in 2022 in 2:29:52. For me, it makes little sense to participate in this event if you are seeking MGC qualification. From my understanding this is a G2 race, so the time required to qualify is 2:27 or better and you must finish top 3 of the Japanese entries. This is a tough ask given the history of the event and conditions. I would be surprised if anyone achieves this time standard even though on paper it looks easy. For Hitomi Niiya, given her excellent time in 2024 you would think it would be easy but given her age, run of injuries and recent form, I'm not convinced. I look forward to seeing how the results turn out.

Hokkaido has the MGC qualifying times listed in the article, which are different from other G2 races given that it is run in hot conditions.

Hitomi Niiya, Arao, and Hibiki Yoshida!! Yoshida will make it interesting and hopefully Niiya can win

My mistake. I just looked at the field and didn't read the article closely enough. Apologies. Yes, you make very good points. I think it's a low bar if the qualification time is set to 2:32:00 even if the conditions are oppressive. I can't imagine Hitomi Niiya not qualifying nor a lot of others. She is currently in a training camp in the US with Rin Kubo so I'm sure it would take a very bad day for her to miss out. Mind you, Ayuko Suzuki won the Hokkaido Marathon in 2018 on debut in a relatively slow time of 2:28:32 to qualify for MGC and then go onto get a spot on the national team for the Tokyo Olympics so perhaps I'm being too harsh. Though I do recall the MGC race was in similarly hot conditions in Tokyo. This time, in Nagoya in Oct 2027 this won't be the case so I think its a matter of encouraging the Japanese athletes from competing domestically rather than abroad. As you said in the article.

Keita Satoh Running New Balance Fifth Avenue Mile

1500 m U20 NR holder Keita Satoh (Nike Swoosh TC) is running this weekend's New Balance Fifth Avenue Mile , the first time that a Japanese man has been invited in the race's 45-year history. In university Sato had to change focus away from middle distance to the half marathon-scale lengths of the Hakone Ekiden stages, but since graduating in March and relocating to Flagstaff he has refocused on the 1500 m, going from 3:43.19 in April in his first 1500 m in almost 4 years to 3:38.30 over the course of 5 races. Fifth Avenue will be his last race before heading back to Japan for one more track 1500 m and some down time. Men's entries with best 1500 m times in last 3 years: Stefan Nillessen (NED) - 3:29.23 (2025) Flavien Szot (FRA) - 3:30.74 (2025) Oliver Hoare (AUS) - 3:31.07 (2024) Jake Heyward (GBR) - 3:31.18 (2026) Titouan Le Grix (FRA) - 3:31.46 (2026) Romain Mornet (FRA) - 3:31.62 (2025) Adam Spencer (AUS) - 3:31.83 (2026) Pieter Sisk (BEL) - 3:31.85 (2025) Gary Martin (...

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."...
