Osako and Murayama Twins Lead National Record Shot at Marugame Half

As strong as its women's field looks, the men's field for the Feb. 5 Kagawa Marugame International Half Marathon is something else.  The half marathon is the sweet spot of Japanese training, the distance that the top university men focus on for the Hakone Ekiden and the best corporate men at the New Year Ekiden national championships.  The official half marathon Japanese national record is 1:00:25 by Atsushi Sato at the 2007 World Half Marathon, but it's pretty common to see the top men running that kind of time on the longest half marathonish-length stages at both Hakone and New Year.  If they all got together, focused, and put the same intensity and drive into a serious half marathon the national record would surely fall, and maybe even the hour mark.  This year's Marugame looks like the best chance to date for that to happen.

Up front: 59:01 man Kenneth Kipkemoi and once-upon-a-time sub-59 man Atsedu Tsegay of Ethiopia.  Positioned just ahead of the Japanese NR: Abraham Kipyatich of Kenya and wunderkind Callum Hawkins of Great Britain.  Right at the level of the current generation of Japan's best: Bernard Kimanyi and Dominic Nyairo of Kenya.  And following them, most of the very best Japan has to offer:

  • 5000 m NR holder Suguru Osako, a member of the Nike Oregon Project with a 1:01:47 Asian junior record half marathon debut and a 1:01:10 equivalent at Hakone.
  • 10000 m NR holder Kota Murayama in his serious half marathon debut, with a 58:26 for 20 km to his name giving him mid-1:01 credentials.
  • His twin brother Kenta Murayama with a 1:00:50 best in Marugame in 2014.
  • Keita Shitara, 1:01:12 at the 2015 National Corporate Half.
  • His twin brother Yuta Shitara, 1:01:48 at the New York Half at age 20 and a 1:00:11 equivalent at last year's New Year Ekiden.
  • Daichi Kamino, 1:01:21 in Marugame two years ago following a spectacular uphill run on Hakone's Fifth Stage and just as ascendant as a young corporate runner.
  • Chihiro Miyawaki, 1:00:53 to win the 2012 National Corporate Half.

There are only two or three names missing from an otherwise perfect collection of Japanese runners to collectively go for the national record, sure to get further support from the massive number of 62 minute-range runners just behind them.  Kenta Murayama told JRN that he and Kota will be going for a time under 1:00:30, at worst under 1:00:50, and the presence of Osako, a training partner of Galen Rupp who was scheduled to go for the U.S.A. NR last weekend, suggests big things.  Marugame usually has ideal weather that contributes to world record-setting depth at quality.  The current forecast calls for cloudy skies and race time temperatures between 2 and 5 degrees Celsius, a little on the cold side but still within a range that would allow for something special.

The Hakone Ekiden is the world's biggest road race, 2 days of road relay action with Japan's 20 best university teams racing 10 half marathon-scale legs from central Tokyo to the mountains east of Mount Fuji and back. The level just keeps going higher and higher , hitting the point this year where there are teams with 10-runner averages of 13:33.10 for 5000 m, 27:55.98 for 10000 m, and 1:01:20 for the half marathon. It's never been better, and with great weather in the forecast it's safe to say this could be one of the best races in Hakone's 102-year history, especially on Day One.

Nagoya Asian Games Test Event Canceled After Insulation Falls From Venue Ceiling

A section of insulation material fell from the ceiling of Nagoya Kinjo Futo Arena, the official venue for squash competition at September's Nagoya Asian Games. There were no injuries, but the city suspended use of the arena until its safety could be guaranteed, resulting in the cancelation of the Asian Games squash test event which was scheduled to have begun on May 14. It is not yet clear whether the arena will be usable for the Asian Games as planned. According to city officials, arena staff found that the insulation material had fallen onto a work walkway 13 m above the ground on the night of May 11. The fallen material was 3.6 m long, 50 cm wide and 2.5 km thick, and was found to be waterlogged. The cause of the accident is unknown, but it is possible that it was caused by rainwater leaking in from the roof. The same insulation material is installed across the entire ceiling, and the city plans to check for the extent of the possible flooding. Asked whether the arena will be re...

Shikama and Njeri Win Sendai International Half Marathon

Shunsuke Shikama (Logisteed) and Tabitha Njeri Kamau (Mitsui Sumitomo Kaijo) won the Sendai International Half Marathon Sunday in Sendai, Shikama in 1:01:31 and Njeri in 1:09:20. Mizuki Nishimura (Tenmaya) was the top Japanese woman at 2nd overall. The men's race went through 5 km in 14:34 and 10 km in 29:22. Shikama ran alongside top competition including Shoki Yamaguchi (Soka Univ.), who has been running well in half marathons this season, and Tokyo World Championships marathon team member Naoki Koyama (Honda). On a course with many small ups and downs, Shikama attacked on a downhill just after 15 km, quickly breaking free of the lead group of 7. 13 seconds up by 20 km, Shikama covered the last 1.0975 km in 3:06 to seal his first Sendai title. A graduate of Juntendo University , Shikama is in his 4th season with Logisteed.
