Osako Tunes Up for Chicago in Redmond

Having both gone under the old 5000 m Japanese national record in the same race in Belgium in 2015, Suguru Osako (Nike Oregon Project) and Tetsuya Yoroizaka (Asahi Kasei) met up again in Redmond, Washington at the September 3rd Labor Day Half Marathon.

Osako, who set the current NR of 13:08.40 in the race in Heusden, ran Redmond as part of his buildup for next month's Chicago Marathon, soloing a 1:01:01 PB to win. Yoroizaka, 13:12.63 in Heusden, finished behind Osako again. Well behind, as in 2nd in 1:04:17 just 8 seconds ahead of top American Gregory Leak.

A PB by 12 seconds, Osako's solo run was the fastest half marathon so far this year by a Japanese man and moved him up to all-time Japanese #9 on a record-legal course. In terms of time and ranking it brought his half marathon up closer to the 2:07:19 he ran in Fukuoka last December, a mark which currently puts him at #7 all-time in Japan. The question is whether it was only bringing his half marathon performance up or whether it shows he is ready for a similar improvement in Chicago. We'll know in just over a month.

A solo 1:01 is really impressive. Hope he has good weather in Chicago.

For the second time in the last three weeks, a Japan-based Kenyan ran the fastest time in the world this year for 10000 m at Yokohama's Nittai University Time Trials series. On October 20th it was 2015 World U18 Championships 3000 m gold medalist Richard Kimunyan (Hitachi Butsuryu), 20, with a 27:14.70  that surpassed Ugandan Joshua Cheptegei's world-leading mark by almost five seconds. This time it was 2018 World U20 Championships 5000 m silver medalist Stanley Waithaka (Yakult), 18, taking almost two minutes off his PB to break Kimunyan's mark with a 27:13.01 win.

Both winners received support from 2014 Commonwealth Games steeplechase gold medalist Jonathan Ndiku (Hitachi Butsuryu), who ran season bests for 2nd place each time, 27:50.38 three weeks ago and 27:28.27 on Saturday. 2013 World U18 Championships 3000 m bronze medalist Alexander Mutiso (ND Software) was also under 28 minutes, running just off his PB at 27:42.16 for 3rd.

Go Ahead and Call It a Comeback - Niiya Breaks Shibui's Course Record in Return to Road Racing

Ladies and gentlemen, Hitomi Niiya is back.

You might remember Hitomi Niiya from the 2013 Moscow World Championships 10000 m, where she led the entire way only to get destroyed over the last lap and finish 5th in 30:56.70. That made her the third-fastest Japanese woman ever over that distance, but not long after that race she quit the sport entirely, getting an office job as far away from athletics as she could and not running for almost five years.

But the pull of the 2020 Tokyo Olympics is strong, and, now 30, early this year she made the decision to try to make a comeback. Under the eye of former men's 800 m national record holder Masato Yokota she ran a 3000 m and two 5000 m time trials on the track between April and October before choosing the East Japan Women's Ekiden for her return to the roads and the longer distances.

The East Japan Women's Ekiden celebrated its 34th running Sunday, 9 stages totaling 42.195 km through the Fukushima countryside with teams from eac…
