Saku Chosei High School's Hamaguchi Runs 13:31.62 at Nittai


2023 National High School Ekiden champion Saku Chosei H.S. was out in force Sunday in the 5000 m fast heats at the 317th Nittai University Time Trials meet in Yokohama. 3rd-year Yamato Hamaguchi ran 13:31.62, the 4th-fastest time ever by a Japanese-born high schooler, and 3rd-year Tetsu Sasaki went under 14 minutes for the first time with an excellent 13:40.02.

The race took place as light rain fell. Hamaguchi and Sasaki ran alongside African university and corporate league runners. From the start they were conservative, staying in the pack as the race went along. With splits of 2:42 and 1000 m and 8:11 at 3000 m the high school record of 13:22.99 set 2 years ago by Saku Chosei alum Hiroto Yoshioka was out of reach, but right til the last sprint Hamaguchi stayed in contact with the lead.

Hamaguchi took almost 7 seconds off his 13:38.40 PB from last year, with Sasaki rewriting his 14:03.51 best by nearly 24 seconds. Both beat Yamanashi Gakuin H.S. 2nd-year Felix Muthiani, who ran 13:42.54. And with Sasaki stepping up to sub-14 territory, the all-Japanese Saku Chosei lineup this season now has five runners under 14 minutes for 5000 m with just over a month to go until the National High School Ekiden.

In Heat 30 before them, Ibuki Sugiyama (3rd yr., Kyushu Gakuin H.S.) ran a PB of 13:47.73 to take the top high schooler spot. Other high schoolers under 14 minutes included Ryo Kurimura (2nd yr., Gakuho Ishikawa H.S.) in 13:48.32, Yota Mashiko (2nd yr., Gakuho Ishikawa H.S.) in 13:49.95, and Kazuma Shino (3rd yr., Saku Chosei H.S.) in 13:58.00. Kiyoshi Miura (3rd yr., Sapporo Yamanote H.S.) ran 13:56.97 in Heat 28, with 1st-year Sei Yoshida (Tokai Sapporo H.S.) just missing out on sub-14 in Heat 29 but still clocking an excellent 14:02.45 PB.

'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...

Meijo Back With Morinomiyako Ekiden CR for National University Title

The last big dynasty school in Japanese women's distance running with 7-straight wins at October's Morinomiyako Ekiden from 2017 to 2023 and 6-straight titles at the season-ending Mt. Fuji Women's Ekiden from 2018 to 2023, Meijo University came back from a 3rd-place finish last year to win the 44th Morinomiyako Ekiden again, leading almost start-to-finish to set a 2:02:21 CR for the 6-stage, 38.0 km course in Sendai. 12 second back in 2nd after the opening leg, collegiate 3000 mSC champ Nozomi Kondo put Meijo out front with a 12:36 CR for the 4.0 km Second Stage, and the rest of the team never looked back. The biggest threat to a Meijo win was on the 9.2 m Fifth Stage, where this year's collegiate 10000 m winner Sarah Wanjiru from last year's runner-up Daito Bunka University started 50 seconds back from Meijo 1st-year Mao Kimura . In taking the 10000 m title Wanjiru had outrun Kimura by over a minute, but today Kimura was a revelation, strong and smooth out fr...
