Karemi Repeats at Record-Setting Kumamoto Kosa 10-Miler

Less than 24 hours after world record-setting 10000 m depth in Hachioji, another record fell at the 40th anniversary Kumamoto Kosa 10-Miler.  Expectations were high that the talented Kenta Murayama (Team Asahi Kasei) would follow up on his twin brother Kota's 10000 m national record in Hachioji by breaking the 45:40 Japanese 10 mile national record set back in 1984, almost a decade before the Murayamas were born.

Murayama came out swinging, running side-by-side with defending champion Jeremiah Thuku Karemi (Team Toyota Kyushu) through a 2:47 opening km, 44:47 pace.  Karemi pushed on but Murayama soon let go and dropped back behind another Kenyan, Charles Ndungu (Team Komori Corp.), picking up company from teammate Kenjiro Mogi.

Running alone Karemi couldn't sustain his course record pace but had no trouble taking a second-straight win.  His time of 45:19 was 32 seconds better than last year and the seventh-best winning time in Kosa history behind only Martin Mathathi (Suzuki Hamamatsu AC), Samuel Wanjiru (Team Toyota Kyushu) and Gideon Ngatuny (Team Nissin Shokuhin).  Not bad company to be in.

Pursuing Ndungu, Murayama and Mogi fell off Japanese NR pace, and with 1 km to go they found themselves mirroring yesterday's 10000 m, where Kota Murayama and his Asahi Kasei teammate Tetsuya Yoroizaka were side-by-side all the way to a photo finish separated by only 0.05 seconds.  This time it was Mogi's turn, though, as he got Kenta Murayama on the line for 3rd, both men clocking 46:08 to come in at #9 on the all-time Japanese list.

Next across the line was this year's top Japanese marathoner Masato Imai (Team Toyota Kyushu) in 46:36, just 1 second off his PB in his first race back since meningitis knocked him out of the summer's Beijing World Championships marathon where he had been a solid medal contender.  Toyota Kyushu runners took the next three places behind Imai, putting the Koichi Morishita-coached team into good position for the Jan. 1 New Year Ekiden corporate men's national championships.  Although not quite as good as Asahi Kasei's position with three men sub-28 yesterday and the top two Japanese men today.

The fast times continued far down the field, with a total of 107 men breaking the 50 minute mark to eclipse the previous record set in Kosa in 1998.  Like at yesterday's historic Hachioji Long Distance meet, the majority of them were using Kosa as a tuneup for the New Year Ekiden, which will be celebrating its 60th anniversary running.  With stellar quality and depth at both races look for something special indeed to happen come January 1.

18-Year-Old Waithaka Runs 10000 m World Leading Time at Nittai - Weekend Roundup

photo by @tsutsugo55225

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…
