Hironaka Breaks 5000 m Junior National Record and 2020 Olympic Standard

Just two weeks after her 19th birthday, Ririka Hironaka, star rookie for 2019 National Corporate Women's Ekiden champions Japan Post, ended the year in style with a nearly 18-second PB of 15:05.40 to break the great Kayoko Fukushi's U20 national record by 5 seconds and become just the second Japanese woman so far to break the 2020 Olympic standard in the 5000 m.

Running at Yamaguchi's National Corporate Women's Time Trials, after Kenyans Martha Mokaya (Canon AC Kyushu) and Hellen Ekarare (Toyota Jidoshokki) led the pack through opening splits of 3:01, 3:04 and 3:03, Hironaka took off in pursuit of the 15:10.00 Olympic standard, covering the next two 1000 m splits in 2:59 and 2:58. Along with breaking Fukushi's 2001-era junior record and clearing the Olympic standard, Hironaka moved up to all-time Japanese #5, following Nozomi Tanaka's all-time #2 15:00.01 at October's Doha World Championships to make this a pretty good year for the 5000 m by Japanese women's standards. With Fukushi's senior national record standing at 14:53.22 it won't be surprising to see either Hironaka or Tanaka go for it in 2020.

The women's 10000 m came up just short of the 31:25.00 Olympic standard but still produced good results across the board. Kenyan Tabitha Njeri Kamau (Mitsui Sumitomo Kaijo) took the top spot in 31:28.45 with teammate Harumi Okamoto next in 31:29.29. Mao Ichiyama (Wacoal) continued her comeback from September's MGC Race Olympic marathon trials with a 3rd-place finish in 31:34.56, a PB by 15 seconds. In 4th, Daito Bunka University 1st-year Yuka Suzuki ran a PB 31:37.88, the 2nd-fastest Japanese collegiate time ever, to add to her 2019 World University Games half marathon gold medal. After a year mostly marked by setbacks, Yuka Hori (Panasonic) wrapped it with a 10-second PB of 31:38.63 for 5th.

5000 m year-leader Tanaka opted to pace teammate Yume Goto (Toyota Jidoshokki TC) in the 3000 m, putting her on track for a 9:05.17 season best before kicking away for the win in 9:01.55. Tanaka plans to race January's National Women's Ekiden before representing Japan at February's Asian Indoor Championships.

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 ru...

Hirayama Breaks Osaka Half CR, Martinez Set Puerto Rican NR

The Osaka Half Marathon took another big step up the domestic half marathon rankings from a mass-participation race run alongside the Osaka International Women's Marathon to one of the country's top-tier races. In the women's race, the debuting Jecinta Nyokabi (Denso) went out fast, only to be run down by veteran Yumi Yoshikawa (Canon AC) by 10 km. Nyokabi faded to 6th in 1:10:41, but Yoshikawa pushed on to a PB 1:09:14 for the win. Rina Shimizu (Noritz), Yuna Takahashi (Shimamura) and Makoto Tsuchiya (Ritsumeikan Univ.) all broke 70 minutes, Tsuchiya taking the Kansai Region collegiate title in 1:09:32 for 4th overall. Everyone in the top 10 who wasn't debuting ran a PB, a mark of how fast the day was even with cold and windy conditions. The men's race went out on sub-61 pace courtesy of Yudai Shimazu (GMO), then got a big injection of speed when Kyuma Yokota (Toyota Kyushu) took off close to 60-flat pace. Yokota opened a 10-second lead by 15 km, but over ...
