Chesang Wins Osaka Women's Marathon in 2:19:31, Yada Drops 2:19:57 Debut NR


This year's Osaka International Women's Marathon was a race run with a high level of methodicalness, starting slower than the planned 3:19/km but ramping up until the lead pack was skimming around the 2:20:15-30 projected finish level. After hitting halfway in 1:10:13 with a group of 6, by 25 km only 4 were left up front, sub-2:19 runners Workenesh Edesa, Stella Chesang and Bedatu Hirpa, and the debuting Mikuni Yada, and when the last 2 pacers stepped off at 30 km it was Yada who went to the front.

Despite never have raced longer than the 10.6 km Third Stage at November's Queens Ekiden where she had helped the Edion team score its first-ever national title, Yada was very, very impressive, fearlessly surging from 12 km and never letting up, even laughing and smiling to fans along the course. When she started sustaining a pace around 3:15/km the projected finish dropped under 2:20 and all the way down to 2:19:28 by 35 km, and even when all 3 of the more experienced runners went by her just after 35 km she fought back to retake the lead.

Chesang pulled away with just over 3 km and ran on to win in 2:19:31, but all the way to the track finish Yada fought back against Ethiopian duo Edesa and Hirpa, digging deep to catch back up and even attack every time they got away. All 3 finished within 3 seconds of each other, Hirpa taking 2nd in 2:19:54 and Edesa 3rd win 2:19:56 a step ahead of Yada, whose 2:19:57 crushed the debut national record. Amazingly, it was only the 2nd time a Japanese woman has ever gone sub-2:20 inside Japan, and even more amazingly Yada said in post-race interviews that the race and the training leading up to it had been fun, not hard.

Yada qualified for the L.A. Olympic marathon trials, and to join her the next 5 Japanese women had to be under 2:27:00. After falling off the lead pack Mao Uesugi held on for 5th in 2:23:07, with Rie Kawauchi coming up from the 2nd group to run down Mizuki Matsuda for 6th in 2:24:16, Matsuda making the cut in 2:26:16 for 7th. Still on track at 40 km after running with Uesugi behind the lead group, Nanaka Izawa blew up hard and shuffled in to 8th in 2:27:45, a PB by 2 minutes but missing Olympic trials qualification.

Making her debut with the goal with the plan of running 2:23 pace to 30 km as a step toward going for the collegiate record next year before her graduation, Amisa Murayama of Mt. Fuji Women's Ekiden runner-up Tohoku Fukushi University ran 100% according to plan. Running down Matsuda and dropping Kawauchi and Mizuki Nishimura, Murayama was in 7th in 1:41:43 when she stopped as planned, 2:23:04 pace versus the 2:26:46 collegiate record. Look for her to crush it next year.

That was an amazing and very exciting race by Mikuni. I'm delighted she got under 2:20 and in doing so she ran the second fastest debut marathon ever by a woman not born in East Africa (only Paula R faster) and became just the 13th non-African woman to break 2:20 (6 of them Japanese).

21yo Amisa Murayama's run was also highly promising and she looks made for the marathon. Next stop for her the World University Cross Country Championships in mid-March (in Italy).

Outstanding marathon debut by Mikuni Yada. Unbelievable time because it was so unexpected. Great race to the finish. Mao Uesugi did well too. Rie Kawauchi was clearly very happy! Nice to see. I was disappointed for Nanaka Izawa and Mizuki Nishimura. Both promised so much but there is still time to get that MGC Qualification. Pace makers did a superb job this year. No issues at the drink stations. Great TV coverage and commentary. 3 years in a row Osaka Marathon has delivered something special. Still can't believe I watched Mikuni Yada do what she did. Please, please, just don't get injured!

Multiple National Records This Weekend

Olympic and World champion Haruka Kitaguchi got the biggest headlines among Japanese athletes this weekend, overcoming a rough last year and a half that included injury and a coaching change to break her own javelin throw NR by over a meter and a half to win the inaugural WA Ultimate Championship in Budapest. U20 WR and Asian AR holder Ziyi Yan opened with a big 68.05, 0.67 m further than Kitaguchi's best-ever from back in 2023. That could have been the end, but Kitaguchi came back from a 61.15 m first attempt to throw a massive 68.92 m NR on her next one, ultimately enough for the win. She still has a long way to go to match the 18-year-old Yan's 71.74 m from May, but it was a clear statement that Kitaguchi is back. Back home at the National Corporate Track and Field Championships in Kyoto, women's pole vault NR holder Misaki Morota continued a solid comeback season of her own, bettering her NR from May by 1 cm with a 4.51 m on her first attempt. Morota took another 3...

On the Loss of the ARRS Database

At some point in the last few months I discovered that both versions of the ARRS database, the static one and the searchable version , are gone. Last week David Monti posted a link to the ARRS history of an event he covered in Race Results Weekly, I guess copying and pasting a link from last year without looking at it, and that reminded me to write something about the loss of the database. The Association of Road Racing Statisticians was basically a one-man show operated from the remote Northern California shores by Ken Young . When the site existed its intro read: The Association of Road Racing Statisticians (ARRS) is an independent, non-profit organization that collects, analyses and publishes results and statistics regarding elite distance running at distances 3000m and longer...The data of ARRS is stored in the ARRS database, which has more than 1.3 million performances from more than 240,000 races by more than 95,000 elite and sub-elite distance runners worldwide...This website ...

Keita Satoh Running New Balance Fifth Avenue Mile

1500 m U20 NR holder Keita Satoh (Nike Swoosh TC) is running this weekend's New Balance Fifth Avenue Mile , the first time that a Japanese man has been invited in the race's 45-year history. In university Sato had to change focus away from middle distance to the half marathon-scale lengths of the Hakone Ekiden stages, but since graduating in March and relocating to Flagstaff he has refocused on the 1500 m, going from 3:43.19 in April in his first 1500 m in almost 4 years to 3:38.30 over the course of 5 races. Fifth Avenue will be his last race before heading back to Japan for one more track 1500 m and some down time. Men's entries with best 1500 m times in last 3 years: Stefan Nillessen (NED) - 3:29.23 (2025) Flavien Szot (FRA) - 3:30.74 (2025) Oliver Hoare (AUS) - 3:31.07 (2024) Jake Heyward (GBR) - 3:31.18 (2026) Titouan Le Grix (FRA) - 3:31.46 (2026) Romain Mornet (FRA) - 3:31.62 (2025) Adam Spencer (AUS) - 3:31.83 (2026) Pieter Sisk (BEL) - 3:31.85 (2025) Gary Martin (...
