Nduta and Akidor Win at Sanyo Ladies Road Race

Alongside the National High School Girls Ekiden, the Nittai University Women's Long Distance Time Trials meet and Sanyo Ladies Road Race 10 km and half marathon made it a busy weekend for women's running in Japan.

At Nittai, Momoka Kawaguchi (Uniqlo) was just off her PB in the 5000 m, winning the A-heat in 15:26.59 by almost 20 seconds over teammate Yume Goto. Nokoka Hosaka (SID Group) took the 3000 m A-heat in 9:25.42, leading the top 5 under 9:30.

At Sanyo, a lead group of 4 went through 5 km in 16:09 in the 10 km before Lucy Nduta (Ehime Ginko) threw in a massive surge to win in a negative split 31:49. Janet Nyiva (Panasonic) held steady for 2nd in 32:17, with Mao Uesugi (Tokyo Metro) fading slightly but holding off the fast-closing Hikaru Kitagawa (Universal Entertainment) for 3rd 32:38 to 32:41. Part of the original lead quartet, Daisy Jerop (Josai Kokusai Univ.) blew up big time in the 2nd half, finishing 16th in 33:34.

Margaret Akidor (Comodi Iida) just missed her CR from last year in the half marathon but still pulled off the repeat win, dropping 10 km CR holder Agnes Mwikali (Kyocera) after 15 km to take 1st in 1:07:52. Mwikali was 2nd in 1:08:01, with Tabitha Kamau Njeri (Mitsui Sumitomo Kaijo) and Nanaka Izawa (Starts) both getting under 70 minutes in 1:09:26 and 1:09:36.

Australian YouTuber Handed Lifetime Ban by Ageo City Half Marathon After Running 1:06 with Another Runner's Bib (updated)

After discussion with their race's chief JAAF referee, on Nov. 27 the organizers of the Ageo City Half Marathon handed down a lifetime ban from their event against 36-year-old Australian Matt Inglis Fox for running the Nov. 15 race wearing the bib number of another JAAF-registered runner. The incident came to light after Fox posted on his personal Instagram account that he had run a PB of 1:06:33 and finished 203rd in Ageo with a 10 km split of 31:03, along with photos and video of himself in the race wearing a bib number beginning with 11. Fox did not appear in the results by name or in that time or place, the closest match being a 1:06:54 gross, 1:06:50 net finish time with a 31:21 10 km split for 18th place in the JAAF-registered division and 209th overall by bib number 1129, registered to a non-Japanese Tokyo-resident club runner. The club runner, Harrisson Uk , readily confirmed that he had given his bib to Fox, saying, "I gave my number to Matt. It wasn't me."...

Batt-Doyle and Strintzos Break Records at Launceston Half

Australians Isobel Batt-Doyle and Haftu Strintzos turned in record-breaking performances to win the McGrath Launceston Running Festival Peppers Silo Half Marathon in Tasmania. Running with a private male pacer, NR holder Batt-Doyle dusted the field with the fastest half marathon ever by an Australian woman on Australian soil, a 1:08:46 CR that put her 2 and a half minutes ahead of runner-up Genevieve Gregson . Last year's runner-up Yumi Yoshikawa was almost a minute back from Gregson in 3rd in 1:12:03, but was almost run down by club runner Ayaka Shimoyamada . Starting slow in her international debut, Shimoyamada moved up from 7th over the 2nd half of the race to finish 4th in 1:12:06, kicking hard in the home straight to try to catch Yoshikawa and momentarily blacking out after finishing. Kaho Onishi was 7th in 1:12:45 in her own international debut. The men's half had pacing set at 2:53/km to try to deliver the first-ever sub-61 half marathon on Australian soil. CR holde...

There weren't any Japanese athletes in action at the Rabat Diamond League meet Sunday, but 2 lower-tier domestic meets produced new national records.
