19-Yr-Old Munakata Breaks Miura's U20 NR to Win Ageo City Half Marathon


The Ageo City Half Marathon is always big, the main race that the coaches of Hakone Ekiden-bound university men's teams use for firming up their entry rosters for the big show. That makes what's basically an idyllic small town race into one of the world's great road races, with depth unmatched anywhere.




One of the top-tier people on the start list at 1:02:07, Kodai Miyaoka (Hosei Univ.) took the race out fast, but the entire pack was keying off the fastest man in the race, Reishi Yoshida (Chuo Gakuin Univ.), 1:00:31. Yoshida reeled Miyaoka in before 5 km and kept things steady in the low-1:01 range, wearing down the lead group to around 10 including his CGU teammate Taisei Ichikawa, a quartet from Izumo and National University Ekiden runner-up Komazawa University, 2 runners from local Daito Bunka University, 2:07:54 marathoner Atsumi Ashiwa (Honda), and Australian Ed Goddard.




Right after 15 km Komazawa went into action, Yudai Kiyama, Hibiki Murakami and Haru Taninaka going to the front and then Kiyama, barely sub-66 for the half marathon but with a 13:37.54 for 5000 m to his name, pushing the pace at 16 km. That dropped most of the pack including Yoshida, and another surge from Murakami cut it down to just him, Kiyama and DBU's 19-year-old Kazura Munakata. Munakata attacked on the downhill of an underpass just before 18 km, and when Murakami and Kiyama dropped he rode that momentum all the way to the win.




Munakata's winning time of 1:01:38 was a new U20 national record, 3 seconds under the old record held by 3000 m SC NR holder Ryuji Miura. Munakata came in with a 28:32.36 best for 10000 m, suggesting he had more in him than his 1:03:13 PB for the half, but his performance here was way beyond anyone's expectations. Kiyama came through in 1:01:59 for 2nd overall, a PB by 4 minutes. As the top 2 Japanese collegiate finishers Munakata and Kiyama scored invitations to next March's United Airlines NYC Half, a development program set up by JRN that has given top-level talent like Paris Olympics 6th-placer Akira Akasaki and former half marathon and marathon NR holder Yuta Shitara their first international racing experience.




Goddard came up to run down Taninaka and others who had fallen off, finishing 3rd overall in a 6-second PB of 1:02:01. "It was a great day," he told JRN post-race. "For years I've looked at the Ageo Half and been like that's just a bucket list race I really want to do. It was a great experience, being in that front pack. They don't lie when they say Japanese races go out pretty quick."

Behind the top 3, almost every single runner in the top 25 ran a PB. Ashiwa and ND Software corporate leaguers both ran sub-63 without breaking their PBs, and likewise for Yuta Nakagawa and Genta Tsuru from Izumo and Nationals winner Koku Gakuin University. CGU's Yoshida was the only other exception, fading to 1:03:00 for 22nd after getting dropped by the Komazawa tag team move at 15 km. Along with Goddard there was a heavier than usual international presence, with Chinese runners Wenjie Wang and Zhongping Chen running PBs of 1:02:38 and 1:03:08 and American Jacob Shiohira running a PB 1:03:19 for 29th overall. The top 3 women all ran PBs too, led by last year's 3rd-placer Aoi Makara in 1:15:31. Conditions might have gotten hot in the last 5 km after the morning cloud cover broke, but overall it was one of the fastest years in Ageo history.

In terms of Ageo's impact on the lead-up to Hakone, Komazawa was the big winner of the day. Along with Kiyama running 1:01:59 for 2nd it had the 3rd, 4th, 7th, 9th, 14th and 16th collegiate finishers, all in sub-63 PBs or debuts. None of its A-list athletes who made up the core of its runner-up teams in Izumo and Nationals ran, meaning Ageo gave it the depth this year's roster has lacked so far. "All our athletes ran well today, especially our 1st-years," head coach Atsushi Fujita told JRN after the race. "This puts us in a very good position."

Daito Bunka also had a good day, Munakata and Kihiro Irihama, 1:02:07 for 6th overall, leading the way but 5 members running new sub-64 PBs. 2024 Hakone Ekiden 3rd-placer Josai University also had the kind of depth-building day Ageo is designed for, 3rd-year Tatsuki Yamanaka and 1st-year Shun Miyake both running PBs under 1:03 and 5 members delivering sub-64 PBs. Koku Gakuin might have been the weak link from the top tier with no new additions to its A-list, but with both Nakagawa and Tsuru still having run under 1:03 it's not really worth reading too much into it at this point. There's still 6 and a half weeks to Hakone, and you can be sure KGU is going to show up at 100% in its shot at joining the tiny club of schools to have swept all 3 major university ekidens in a single season.

'CAS Clears Japan’s Olympic Silver Medallist Ikeda of Doping, Overturns Ban'

https://www.aljazeera.com/sports/2026/10/23/cas-clears-japans-olympic-silver-medallist-ikeda-of-doping-overturns-ban The AIU's missteps in this case cost Tokyo Olympics and Oregon World Championships 20 km race walk silver medalist Koki Ikeda , a Toyo University graduate who competes for the Asahi Kasei corporate team, the chance to represent Japan at a home soil World Championships last year. It is almost unheard of for an athlete to successfully fight a biological passport suspension as Ikeda did, making this a highly significant case. The CAS' press release about its decision stated: "The Panel stressed that the Athlete did not merely assert his position on the ABP abnormalities but adduced very extensive evidence in support of his explanations. In this highly complex case, the evidence brought during the CAS proceedings was far more abundant and specific than during the first instance proceedings with the WA Disciplinary Tribunal, implying the CAS Panel had further ...

Waseda Leads Top 7 Teams Under Izumo Ekiden CR, Ivy League Best-Ever 3rd (updated)

3rd last year, Waseda University scored its first Izumo Ekiden win since 2010, taking almost 2 minutes off the CR and leading the top 7 teams under the old record of 2:07:51 for the complete 6-stage, 45.1 km course. Waseda was 16 seconds back in 7th after the First Stage, but its 2nd runner Ojiro Honda made that up easily and put them 6 seconds out front. A massive 22:56 CR for the 8.5 km Third Stage by Shadrack Kipkemei (Nihon Univ.) dropped Waseda back to 2nd even though its runner Ryuki Suzuki broke the old CR too, but back-to-back CR on the next 2 stages by 1st-year Haruki Niizuma and Shunpei Yamaguchi put anchor Shinsaku Kudo out of reach of the rest of the field. Kudo duly won the 10.2 km anchor stage in 29:00, bypassing a 2:06 time entirely for a new 2:05:56 CR, just under 2:48/km average pace for the complete course. Defending champ Koku Gakuin University struggled a bit in the first half of the race but came on strong in the longer second half with 4th and 5th runners...

Morinomiyako Ekiden Preview

The university men's ekiden circuit is 100% dominated by schools from the Tokyo-area Kanto Region, but for women it's more geographically diverse, the last two big dynasty schools being the Tokai Region's Meijo University and the Kansai Region's Ritsumeikan University with Kanto's Daito Bunka University a perpetual close 2nd at both of the main races, Sunday's Morinomiyako Ekiden and December's Mt. Fuji Women's Ekiden . Last year Kanto's Josai University scored upset wins at both Morinomiyako and Mt. Fuji , to make it a rare Kanto sweep. At Morinomiyako DBU was 2nd yet again with Meijo 3rd and Tohoku region local Tohoku Fukushi University a surprise 4th to hold 2024 winner and top Kansai team Ritsumeikan back to 5th. At Mt. Fuji Tohoku Fukushi almost pulled off a shock win on the anchor stage before Josai came back on the final climb, bumping DBU down to 3rd and Meijo to 4th, with Ritsumeikan 5th there too. Fresh names at the top of the list a...
