Muthini Breaks Hakodate Half Course Record


Soka University's Stephen Muthini broke the course record at the Hakodate Half Marathon Sunday to win in a PB 1:01:08. Muthini led from the early going, dragging a lead group of 10 behind him. Past 10 km he picked up the pace, cutting the lead group down to 6, including 2025 Tokyo World Championships marathon team member Yuya Yoshida (GMO). Near 15 km Takuma Yamakawa of Komazawa University went to the front, but Muthini was quick to retake the lead and gradually pulled away from Yamakawa and Yoshida. Yoshida ended up 2nd behind Muthini in a PB of 1:01:23, with Yamakawa 3rd also in a new PB of 1:01:25. Times were fast across the board, with 8 of the top 10 men running lifetime PBs.

Yoshida, a 2-time winner of the Fukuoka International Marathon including a 2:05:16 CR last December, is Japan's leading hope of ending its dry spell of World Championships marathon medals, the last being Tsuyoshi Ogata's bronze at the 2025 Helsinki World Championships. His Tokyo Worlds teammates Ryota Kondo (Mitsubishi Juko) and Naoki Koyama (Honda) struggled, Kondo 19th in 1:03:25 and Koyama 62nd in 1:06:16.

In the women's race, Mizuki Matsuda (Daihatsu) won in 1:09:48, splitting 16:21, 32:44, 49:26 and 1:06:08 en route. Tenmaya's Shiori Yoshizono and Mizuki Nishimura were 2nd and 3rd just over 1:10, with Tokyo Worlds women's team member Kana Kobayashi (Otsuka Seiyaku) 5th in 1:11:37. Marathon national record holder Honami Maeda (Tenmaya) was 6th in 1:11:54 in a tuneup for September's Berlin Marathon.

In the marathon, Minoru Kameda took the men's race in a PB of 2:19:46, the only runner under 2:20. Kasumi Takahama was the women's winner in 2:55:01.

Takei Breaks Gold Coast Marathon CR in Dominant Japanese Run

Japanese men showed up in force at the 45th ASICS Gold Coast Marathon Sunday in Australia, taking the top 6 spots and 8 of the top 10 led by a 2:07:33 course record by Yuki Takei . Expert pacing by World Marathon Majors-bound Tsubasa Ichiyama and Masato Arao kept things on track to break the 2:07:40 CR by 30 seconds until Arao stepped off at 30 km, a 30 km that saw at least two falls, one by 2:08:40 runner Ryoma Takeuchi at 23 km and another by debuting 61-minute half marathoner Tatsuya Tsunashima at 27 km. In Tsunashima's case it was enough to knock him out of the race when he hit his head on the pavement, send to the hospital post-race for examination. When Arao stepped off former Aoyama Gakuin University ekiden specialist Aoi Ota went straight to the front, looking to make up for a stellar and predictable DNF at this year's Tokyo Marathon in prep for Berlin by getting an easy finish under his belt. Right on him was Yuki Takei , 2:08:06 in Osaka the week before Tokyo. ...

National Track and Field Championships Highlights

Japan's National Championships happened Friday through Sunday at Tokyo's National Stadium, the same track where September's World Championships will take place. The biggest result of the weekend came in the women's 800 m, where high schooler Rin Kubo cleaned up the mess caused last when she became the first Japanese woman under 2 minutes but did it at a JAAF-sanctioned time trial meet that hadn't been registered to the World Athletics calendar. In Saturday's final she bettered that time with a 1:59.52, making it a national record that WA will actually recognize. The only other record set came in the women's 5000 m on Friday, where NR holder Nozomi Tanaka set a meet record 14:59.02 to win a competitive race over Ririka Hironaka , 2nd in 15:12.61, and Kana Mizumoto , 3rd in a big PB of 15:13.19. Tanaka doubled back in the 1500 m Sunday, duly winning in 4:04.16. Veteran Tomoka Kimura ran a PB of 4:09.88 for 2nd, giving a big boost to her chances of making i...
