Yamaguchi Wins Setagaya 246 Half, Orita Takes Miyako

It's the point in the season where Hakone Ekiden-bound university coaches are farming out their squads to half marathons to sort through the contenders to make their 16-runner Hakone entry rosters. Next weekend's Ageo City Half Marathon is the biggest of them, but two key races happened today. In rainy conditions at the Setagaya 246 Half in Tokyo, Shoki Yamaguchi (Soka Univ.) won a sprint finish against sub-60 man Paul Kuira (JR Higashi Nihon), Kuira overtaking Yamaguchi after Yamaguchi had pulled away over the last km but Yamaguchi fighting back on the track. Both clocked 1:01:46, but Yamaguchi succeeded in snagging the win away from Kuira right before the line.

In 3rd, Aito Sato led a massive group from 2025 Hakone champ Aoyama Gakuin University with a PB of 1:01:57 for 3rd. 5 other AGU runner were under 63 minutes, all but one breaking 62:30 and most in PBs, with Kotaro Suzuki (Chuo Univ.), 8th in 1:02:28, and Yota Aoteki (Hosei Univ.), 10th in 1:02:46 breaking up AGU's control of the rest of the top 10. Former Nitori member Kaede Okajima (Kanto RC) won the women's race in 1:18:07, with 50-year-old Junko Ganbara running an excellent 1:20:09 for 3rd.

AGU's Sota Orita, 13:28.78 for 5000 m in high school, was at the Miyako Salmon Half in Iwate for his half marathon debut instead of Setagaya. Orita soloed a 1:02:51 for the win, opening up 9 seconds on Kosei Niitani from National University Ekiden champion Komazawa University, 2nd in a PB of 1:03:00. Also debuting, AGU's Ao Funakoshi ran 1:03:02 for 3rd. The duel between AGU and Komazawa was a preview of what is probably to come at Hakone less than 2 months from now.

Atsumi Nagashima (Saysky) won the women's race in Miyako in 1:25:15.

Osako Breaks Marathon NR for 3rd Time - Weekend Roundup

It looked like it was going to be a big weekend, and it delivered. For the 3rd time in his career Suguru Osako broke the men's marathon NR, running 1 second under the standing record to take 4th in the Valencia Marathon in 2:04:55. All the way to 40 km he was steady on 2:58/km, 2:05:10 pace, and like a surprising number of other people in both the men's and women's races, there was a massive jump over the last 2.195 km from his projected finish time to his actual one. His run put Osako back on top of the Japanese charts, put the average of Japan's 10 fastest marathon times of the year under 2:06 for the first time, and got him into the L.A. Olympics marathon trials. Valencia has been trying to get top-tier Japanese athletes to come for years, and now that they finally managed to do it it paid off in a big way. Expect more next year. Back home, former Takushoku University captain Derese Workneh won a 3-way race against Toyota teammates Kazuya Nishiyama and Bedan Ka...
