Kawauchi Takes Over Three Minutes Off Own 50 km National Record at Okinoshima Ultra

by Brett Larner

Continuing a season that seems to show him returning to his best form, Yuki Kawauchi (Saitama Pref. Gov't) took over three minutes off his own national record as he won the hilly Okinoshima Ultramarathon's 50 km division in 2:44:07.  Run on the island where Kawauchi's late father was born, the Okinoshima Ultra is a Father's Day fixture on Kawauchi's calendar.  The course features a relatively flat first 10 km, three 100 m+ tall ups and downs between 10 and 30 km, and an undulating last 20 km capped by one more major hill with 5 km to go.


"The weather conditions were better than usual, so I decided to go for the course record," Kawauchi told JRN post-race.  Where he has typically opened the first 10 km in 33-34 minutes in past years, this year he went out red-hot, splitting 31:07, 2:11 marathon pace, before hitting the hills.  Over the next 20 km he was slightly slower than in the last two years, but even so with a 1:38:21 split at 30 km projecting to a 2:43:55 finish he was just off pace to hit the world record of 2:43:38.  "Mid-race it got sunny and the wind came up, so it got much tougher," Kawauchi said.


The hills and weather kept the world record just out of reach, but Kawauchi's 2:44:07, 2:18:30 marathon pace, still marked a massive improvement on his 2:47:27 national record two years ago in Okinoshima.  Only two people have ever run faster, South Africa's Thompson Magawana with a 2:43:38 split in the 56 km Two Oceans ultra and American Josh Cox with a 2:43:45 at the Rock 'n' Roll Arizona Marathon where Cox ran to a local track after finishing the marathon and ran laps until he had covered 50 km, a mark recognized by USATF as a national record but not considered by others to have been run in a bona fide competition.  "To be honest, it would be very hard to get the world record on this course," Kawauchi said.  "I think I'd like to go for it at Lake Saroma."


At last year's Okinoshima Kawauchi's younger brother Yoshiki Kawauchi made his 100 km debut, suffering home mightily in 11:21:52.  A year older and wiser, Yoshiki returned this year to win the 100 km division in 7:20:31.  It's not every day that you get to run a four-hour PB.  Given the toughness of the 100 km course's hills it's a time that puts him close to national team level if he ever decides to run the fast Lake Saroma course where both the current men's and women's 100 km world records were set.

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…
