Ageo City Half Marathon Entry List Highlights and Streaming


Ekiden season rolls on with Sunday's Ageo City Half Marathon. Most of the universities bound for the Hakone Ekiden, including this season's Izumo Ekiden winner Koku Gakuin University and National University Ekiden winner Komazawa University send big squads to Ageo every year so their coaches can thin down the list of contenders for their 16-name Hakone entry roster.

Since 2012 there's been the extra motivation for top talent to run Ageo in JRN's partnership program between Ageo and March's United Airlines NYC Half to bring the top 2 Japanese collegiate finishers in Ageo and their coaches to run in NYC. That's had an impact, with people like this year's Berlin Marathon runner-up Akira Akasaki and former half marathon and marathon NR holder Yuta Shitara having gone through the program.

You never really know from the entry lists who's actually going to show up to run in Ageo, but it's always an incredibly deep race with no parallel anywhere except maybe Spain these days. Koku Gakuin and Komazawa have both entered some heavy hitters, with Komazawa featuring last year's 2nd and 3rd-place collegiate finishers in Ageo Yudai Kiyama, 1:00:32, and Hibiki Murakami, 1:01:46, both returning along with teammates Shunsuke Kuwata, 1:01:09, Kaisei Yasuhara, 1:02:33, and Seiryu Morishige, 1:02:51. Koku Gakuin has Rui Aoki, 1:00:47, Goki Takayama, 1:01:42, Hayato Oguma, 1:01:46, Arata Iiguni, 1:01:51, Junpei Kakazu, 1:02:18, Kuranosuke Yoshida, 1:02:29, Shoma Kamada, 1:02:49, and Kotaro Kodama, 1:02:56. With 2025 Hakone winner Aoyama Gakuin University having seriously upgraded its half marathon credentials at races last weekend, both Komazawa and Koku Gakuin will be looking to improve on those numbers here.

Other top entries include Patrick Kamau (Jobu Univ.), Akito Noda (Hosei Univ.), Renato Ogata (Toyo Univ.), and Rinta Miyaoka (Waseda Univ.). Five runners with 10000 m bests under 29 minutes are entered to debut, led by Juntendo University's Riito Ikema at 28:29.80.

The race starts at 9:00 a.m. local time Sunday, with streaming getting rolling at 8:40. Check the event's official Twitter account too. JRN will be on-site at Ageo and posting pictures and video from the lead car during the race.

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 (...

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...
