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.

Hassan Runs NR/CR for Osaka Win, Dibaba Hits Women's CR, Yoshida and Shuley Earn Legends

This was maybe the most entertaining marathon in years. After rocking the 2nd leg at last year's Hakone Ekiden Hibiki Yoshida (Sunbelx) ran an incredible 1:01:01 CR for the 21.9 km New Year Ekiden 2nd leg last month, equivalent to a 58:47 half marathon. That predicted a 2:03:27 marathon if he ever ran one, and when Yoshida announced he was debuting at this year's Osaka Marathon he wasted no time in saying it'd be a shot at the 2:04:55 NR. Things went out fast enough with a 14:50 split through 5 km, 2:05:11 pace, but Yoshida just couldn't hold back and took off at 8 km. He clearly DGAF about what was probably going to happen as his projected finish kept getting faster, 2:04:41, 2:04:15, 2:03:51, 2:03:40, edging closer and closer to what his New Year time predicted, but not helped along by the fact that he missed 4 out of his first 5 drink bottles. People laughed, and then cheered him on. 30 km was the first time he slowed, his finish projection dropping to 2:03:53, an...

2026 Tokyo Marathon Elite Field

The Mar. 1 Tokyo Marathon has great fields this year, so let's get right to it. The women's field has 3 of last year's top 10, winner for the 2nd year in a row and Tokyo CR holder Sutume Asefa Kebede , 3rd-placer and 2025 Chicago winner Hawi Feysa , and 5th-placer and 2025 Berlin winner Rosemary Wanjiru , plus 2024 Valencia winner Megertu Alemu , 2025 Prague winner Bertukan Welde , 2024 Paris winner Mestawut Fikir , 2024 Osaka winner Waganesh Mekasha , former WR holder Brigid Kosgei , and a lot more. Japanese hopes pretty much go to all-time #7 Ai Hosoda , 2:20:31 in Berlin 2024 but who announced this month that she is retiring after Tokyo despite having qualified for the 2028 Olympic marathon trials with her 2:23:27 for 6th in Sydney last year. Other internationals include Canadian Malindi Elmore , American Sara Hall , a big Chinese group led by Yuyu Xia , Poland's Aleksandra Brzezińska and Australian Vanessa Wilson . The men's race has 5 of last year's top 1...

Osaka Marathon Preview

The Osaka Marathon is Sunday, one of Japan's biggest mass-participation races and the next stop on the calendar for its elite marathoners hoping to qualify for the L.A. Olympics marathon trials in the fall of 2027. Last year it snowed mid-race, but this year is looking warmer than ideal given the season, with sunny skies, almost no wind, and temps forecast to be 11˚ at the start and rising to 19˚ by the time the winners are finishing. NHK is broadcasting Osaka with a heavy emphasis on the men's race, and if you've got a VPN you should be able to watch it from overseas. There's also official streaming on Youtube starting at 8:30 a.m. local time, although it doesn't look like it's the same as what NHK will be showing. Given Osaka's history at the elite level as the continuation of the men-only Lake Biwa Mainichi Marathon, the women's field is small relative to the men's, just enough to tick World Athletics' label requirements and with almost no do...
