Aizawa Goes Sub-28, Suzuki Returns - Weekend Track Review

Elite road racing returned to Japan this weekend with Saturday's Hakone Ekiden qualifier and Sunday's National Corporate Women's Ekiden qualifier, but there was still a load of track action at every level.

Saturday in Miyazaki, one of the stars of this year's Hakone Ekiden, Akira Aizawa made his corporate debut for New Year Ekiden national champ team Asahi Kasei with a 27:55.78 win in the Miyazaki Time Trials 10000 m, his first time going sub-28. His former Toyo University teammate Kazuya Nishiyama was 2nd in 28:03.94, the best time by a Japanese collegiate student so far this year. Asahi Kasei had eleven men in the race under 29 minutes including Rio Olympics marathoner Satoru Sasaki, putting them in good position for another national title defense come Jan. 1. Kyoto's Ritsumeikan University had three men under 29, setting them up as a threat to the Kanto Region's monopoly on the podium at the Nov. 1 National University Men's Ekiden.

Defending corporate women's national champ Japan Post fielded most of its team at the Tokai University Time Trials meet in Kanagawa. Tokyo Olympics marathon team member Ayuko Suzuki returned from a long injury to win Saturday's 5000 m in heavy rain in 15:57.16 before doubling in Sunday's 3000 m with a 9:19.07 for 2nd behind teammate Hikari Onishi, winner in 9:18.43. Onishi was 2nd in the 5000 m in 15:57.96, with club runner Shiho Kaneshige (GRLab) the only other woman to break 16 at 15:59.52. Junior teammate Ririka Hironaka came back from her sub-15 5000 m last month to win Sunday's 1500 m in a PB of 4:16.48. Steepler Philemon Kiplagat (Aisan Kogyo) won Saturday's men's 5000 m A-heat in 13:33.92, with Alexander Mutiso (ND Software) taking Sunday's 10000 m A-heat in 28:06.21.

National High School Ekiden boys' course record holder Sera H.S. likewise tuned up for championship ekiden season at Sunday's East Hiroshima Nighter meet. The Sera girls took the top four spots and seven of the top ten in the 3000 m A-heat, Kenyan Theresa Muthoni winning in 9:18.25. In the men's 5000 m A-heat Sera had four boys under 14 minutes, Kenyan Cosmas Mwangi winning in 13:38.14, 2nd-years Shota Morishita and Shota Shiode 4th and 5th in 13:57.16 and 13:57.88, and 3rd-year Konosuke Shintani 8th in 13:59.32.

The Sera boys weren't the only high schoolers under 14 minutes over the weekend. At Saturday's Sayagatani Time Trials meet in Fukuoka, Jiyugaoka H.S. 3rd-year Ayumu Yamamoto ran 13:56.31 for 7th, beating Rio Olympics marathoner Hisanori Kitajima (Yasukawa Denki) among others. Kitajima's teammate Kiyoshi Koga returned from a 1:00:49 runner-up finish at this year's National Corporate Half Marathon to take the top spot in 13:39.70.

Multiple National Records This Weekend

Olympic and World champion Haruka Kitaguchi got the biggest headlines among Japanese athletes this weekend, overcoming a rough last year and a half that included injury and a coaching change to break her own javelin throw NR by over a meter and a half to win the inaugural WA Ultimate Championship in Budapest. U20 WR and Asian AR holder Ziyi Yan opened with a big 68.05, 0.67 m further than Kitaguchi's best-ever from back in 2023. That could have been the end, but Kitaguchi came back from a 61.15 m first attempt to throw a massive 68.92 m NR on her next one, ultimately enough for the win. She still has a long way to go to match the 18-year-old Yan's 71.74 m from May, but it was a clear statement that Kitaguchi is back. Back home at the National Corporate Track and Field Championships in Kyoto, women's pole vault NR holder Misaki Morota continued a solid comeback season of her own, bettering her NR from May by 1 cm with a 4.51 m on her first attempt. Morota took another 3...

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 (...

On the Loss of the ARRS Database

At some point in the last few months I discovered that both versions of the ARRS database, the static one and the searchable version , are gone. Last week David Monti posted a link to the ARRS history of an event he covered in Race Results Weekly, I guess copying and pasting a link from last year without looking at it, and that reminded me to write something about the loss of the database. The Association of Road Racing Statisticians was basically a one-man show operated from the remote Northern California shores by Ken Young . When the site existed its intro read: The Association of Road Racing Statisticians (ARRS) is an independent, non-profit organization that collects, analyses and publishes results and statistics regarding elite distance running at distances 3000m and longer...The data of ARRS is stored in the ARRS database, which has more than 1.3 million performances from more than 240,000 races by more than 95,000 elite and sub-elite distance runners worldwide...This website ...
