Ngetich and Mutiso Take Down Tokyo Legacy Half CR


In its 5th edition the Tokyo Legacy Half Marathon scored 2 new course records via Kenyans from the Ikaika agency, with 10 km WR holder Agnes Ngetich blasting 3 minutes off the old record to win by over 4 in 1:04:23, and Alexander Mutiso skimming just 1 second under the CR for the win by 5 seconds in 59:51. The 2 races played out completely differently, even if the paydays were the same for the winners.

Surrounded by an envelope of male runners all the way to the final 100 m, Ngetich was out hard on the downhill in the first 5 km, hitting it on sub-64 pace in 15:08 before leveling out on the flat middle 10 km. Her next 2 splits projected to 1:04:09 and 1:04:17, and even with the uphill back to the stadium in the last 5 km she didn't fall far off from that, winning in 1:04:23.

Runner-up Tabitha Njeri Kamau was nearly a mile back in 1:08:28, with Kamau's Mitsui Sumitomo Kaijo teammate Kazuna Kanetomo dropping a 1:10:17 PB for 3rd. Now an independent, track Olympian Kaede Hagitani was the only other woman in the top 10 to PB, taking 5th in 1:10:49.

Mutiso led the men's race out on 59:51 pace through 5 km, then picked it up slightly after hitting the flat to hit 10 km on 59:39 pace. That cut the lead group down from 18 to 14, out of which the only Japanese athletes were Shota Shiode, Akira Aizawa, Itta Tameike and Shunya Kikuchi. By 15 km the pace had slowed very slightly with a 59:44 projection, leaving only Amos Kiprotich, James Mutuku and Kiprono Sitonik in contact with Mutiso and Tameike and Aizawa a few seconds back in a small 2nd group.

Mutiso attacked the uphill to drop the other Kenyans, digging down hard on the track at the end to clip the CR for the win in 59:51. Sitonik broke 60 for the first time in 59:56 for 2nd, and 7 of the other 8 athletes in the top 10 likewise set new PBs. Tameike had a massive run, taking almost 3 minutes off his best for a new one of 1:00:13 in 5th, beating even the 1:00:23 equivalent he ran on the 23.1 km Second Stage at Hakone in January and tying him with Shunsuke Kuwata at all-time Japanese #6. Aizawa also ran a 1-minute of 1:00:26 for 6th, an encouraging sign ahead of his planned appearance in Fukuoka in December.

With its uphill finish the Tokyo Legacy Half is not exactly the fastest course in Japan and often suffers from warm conditions, including today. But this year's results had it approaching the same tier as the other super-deep Japanese half marathons, including yesterday's Hakone Ekiden Yosenkai:

sub-60: 2
sub-61: 9
sub-62: 23
sub-63: 46
sub-64: 65
sub-65: 74
sub-66: 89
sub-67: 98

Expect that to grow in the next couple of years with the introduction of a seeded bracket to the New Year's Ekiden, eliminating the need for the top bracket teams to run a regional qualifier ekiden at the beginning of November.

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...

Akasaki PBs in Chicago, Takeuchi 2nd in Perth

Four elite-level Japanese athletes were at the Chicago Marathon Sunday. In the women's race, Yuka Akasaki (Kraftia), 6th in the marathon at the Paris Olympics, ran the second-fastest time of her career, 2:23:18 for 11th. Her husband Akira Akasaki (Kraftia), also 6th in Paris and runner-up in Berlin last year, better his PB by 28 seconds with a 2:05:47 for 9th, the fastest time this year by a Japanese man and his second-straight World Marathon Majors top 10 finish. NR holder Suguru Osako (Li Ning) was about 3 minutes off his goal of a new Asian record with a 2:07:34 for 14th, with half marathon NR holder Tomoki Ota (Toyota) struggling a bit to find his feet in his marathon debut, running 2:11:52 for 26th off a 1:02:57 first half. At the Perth Running Festival marathon in Australia, 2025 Warsaw Marathon winner Ryoma Takeuchi (ND Software) had a great head-to-head race against Kenyan Dominic Ngeno , together through 10 km, then dropping as far as 1:42 behind at one point before...

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."...
