Tokyo Legacy Half Marathon Preview and Streaming


Following Saturday's Hakone Ekiden Yosenkai qualifier half marathon, the weekend's other big half is Sunday's Tokyo Legacy Half Marathon. The Tokyo Marathon Foundation has been trying to get this race off the ground for the last few years, and it is pretty cool. Starting and finishing on the track in the National Stadium built for the 2021 Tokyo Olympics and following basically the same course as the one originally planned for the Tokyo Olympics and Paralympics, the MGC Race Olympic marathon trials, and last month's Tokyo World Athletics Championships marathon, it's quickly gotten popular as a mass participation race.

But as an elite race it's got a few problems. The uphill finish that was such an important strategic part of the MGC and World Championships marathons means it'll never be as fast as it could be. And its timing in the middle of ekiden season severely limits the number of Japanese athletes and Japan-based Africans who can run it, especially for women as the Princess Ekiden qualifying race for the National Corporate Women's Ekiden is the same day. There's a little bit of a silver lining there, as the National Corporate Federation is looking at finally adding a seeded bracket to the New Year Ekiden specifically to free up top-level people from top-tier teams to run the Tokyo Legacy Half.

But anyway, the fields are what they are, and they're not bad. On the women's side Janet Nyiva and Kaede Kawamura are the only sub-70 women in the race, but they've got some interesting competition from Rebecca Mwangi, debuting off a 31:13 road 10 km this year, Gold Coast Marathon CR breaker Yuki Nakamura, and returning former track star Kaede Hagitani. Ethiopian Meskerem Mamo hasn't raced since 2021 and didn't do anything longer than 5 km even back then, but she's set to debut here too for whatever reason.

Tokyo Olympics 10000 m gold medalist Selemon Barega is the heavy favorite in the men's race, where his main competition is collegiate half marathon record co-holder Richard Etir fresh off Monday's Izumo Ekiden, sub-60 man Benard Langat, and 2:05:43 marathoner Victor Kipchirchir. The currently fastest Japanese man in the field is Kotaro Kondo at 1:01:26, and right behind him Suguru Osako and Yohei Ikeda are running in prep for the Valencia Marathon in December. Hakone Ekiden First Stage CR holder Yamato Yoshii will be running his first half marathon since going to the corporate leagues, and Masato Arao will also be back on the roads after his breakthrough 2:07:42 PB for 6th at the Sydney Marathon in August.

The race will be streamed live starting at 7:45 a.m. local time Sunday, with the wheelchair race starting at 8:00 and the main event at 8:05.

Fantastic to see Kaede Hagitani's name in the starting line up. I remember reading an article a while back saying she was returning to athletics but then she never appeared in any races of note that I could find and no updates either on whether she was injured and perhaps decided to retire again. I hope she performs well as I believe she intends to qualify for the Los Angeles Olympics in the marathon. Also interested to see how Yuki Nakamura goes in this. She's been relatively quiet this year compared to her great 2024 season.

always fascinating seeing how these elite lineups come together. The Tokyo Legacy course looks brutal with that uphill finish but still such a special event to run through the Olympic route. I’m training for a marathon next year, so I love following these build-up races and seeing how the pros handle the conditions and pacing strategies.

Hakone Ekiden Qualifying Race Entry Roster Sizes Increased from 14 to 16

Hakone Ekiden organizers KGRR have announced details for the qualifying half marathon for next year's 103rd Hakone Ekiden. The Yosenkai qualifying race will be held Oct. 17 in Tachikawa, Tokyo. The combined times of the 10 fastest finishers from each participating team will be used for team scoring, with the 10 fastest teams going on the the main event next January and top-placing individuals from teams that do not qualify being names to the Kanto Region Student Alliance select team. One change from previous years is that the number of runners each school can enter has been increased from 14 to 16. Teams will still only be allowed to have from 10 to 12 athletes on the starting line, but the move gives coaches greater flexibility in making the final decision on their starting rosters. No changes have been made to the qualifying times of 34:00 for 10000 m or 1:13:00 for the half marathon, and the new earlier starting time of 8:30 a.m. introduced last year in an effort to mitigate ...

Japan's Team for Nagoya Asian Games

The JOC announced the full lineups for the men's and women's teams for September's Nagoya Asian Games . Being hosted in Japan the Asian Games are a pretty big deal, and it's pretty close to the maximum of 2 athletes per event. The men's and women's triple jump, the women's 400 m and the women's discus throw only have 1 athlete on the Japanese team, and it's a big FU to the shot putters apparently as nobody was named to either the men's or women's teams even though people ranked lower in the World Athletics Asian rankings than top JPN shot putters Daichi Morishita and Chiharu Saka did make the team in other events. But, let's focus on what it is, not what it isn't. Going off this week's Asian rankings 8 men and 5 women are ranked #1 in their event, with a total of 19 men and 14 women ranked in the top 3. Factor in a limit of 2 per nationality and the relays and Japan's chances of scoring a great medal haul are looking good. M...

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."...
