Weekend Track Roundup - A National Record for Suzuki, Fast Veterans and Faster High Schoolers

by Brett Larner

Japan's track circuit was busier than usual this weekend with the move of the National Corporate Track and Field Championships from mid-September this year along with time trial meets nationwide as teams prepare for ekiden season.  At the Corporate Championships, Team Kyudenko's Kenyan ringers Selly Chepyego Kaptich and Paul Tanui were the stars of the show, doubling with wins in the fastest heats of the 5000 m and 10000 m.  Chepyego, the Copenhagen World Half Marathon bronze medalist started things off on Friday night with a 31:38.54 win over Asian Games 10000 m bronze medalist Ayumi Hagiwara (Team Uniqlo), who ran a PB 31:41.80, the best time this year by a Japanese woman, to lead three Japanese women under the Beijing World Championships standard of 32:00.00.  Chepyego returned Sunday to win the 5000 m in 15:14.45 just ahead of ascendant first-year pro Ayuko Suzuki (Team JP Post) whose 15:14.96 was also the best this year by a Japanese woman.  Hagiwara took 3rd in 15:24.56.

On the men's side, Moscow World Championships 10000 m bronze medalist Tanui had a close one against 2013 World XC junior silver medalist Leonard Barsoton (Team Nissin Shokuhin), winning in 27:17.82 to Barsoton's 27:20.74 PB.  All told five Kenyans and two Ethiopians broke 28 minutes, with former Tokai University ace Tsubasa Hayakawa (Team Toyota) taking the top Japanese position at 10th in 28:23.64.  Like Chepyego, Tanui was back on Sunday to win the fastest 5000 m heat in 13:22.51 for the double national title.

Other distance news at the Corporate National Championships came in the junior women's 3000 m, where Aomori Yamada H.S. graduate Rosemary Monica Wanjiru (Team Starts) ran a meet record 8:48.44 to win by 19 seconds.  In other events, Yusuke Suzuki (Team Fujitsu) became the first Japanese man to go under 39 minutes in the 10000 m racewalk, taking over 40 second off the old mark to set a new national record of 38:27.09.  Team Sumitomo Denko set a men's 4x100 m relay meet record 38.94, with runner-up Mizuno also under the old record.  Asian Games men's 3000 mSC 4th-place Jun Shinoto (Team Sanyo Tokushu Seiko) made up for his disappointment and just missing the medals in Incheon, winning in 8:34.37.  London Olympics men's javelin throw competitor Genki Dean (Mizuno), struggling with injury since going pro, did not start in the javelin but instead turned up in the discus, finishing 14th of 18 with a throw of 42.28 m.

Elsewhere, 39-year-old Mari Ozaki (Team Noritz), the world record holder for most sub-16 minute 5000 m performances, added at least #76 to her legacy with a 15:54.91 win at the Nighter Time Trial in Marugame.  Virtually all of the other women in the top ten were high school or collegiate athletes half her age, several of them also breaking 16 minutes.  The best high school performances came at the Shizuoka Long Distance Time Trials meet, where Toyokawa H.S. senior Azusa Sumi and Tokiwa H.S. junior Harumi Okamoto just missed joining the small Japanese sub-9 club in the 3000 m, battling to the line with Sumi winning in 9:00.89 and Okamoto 2nd in 9:00.91.  Both bumped 2014 Youth Olympics 3000 m gold medalist Nozomi Musembi Takamatsu (Osaka Kunei Joshi Gakuin H.S.) out of the all-time Japanese high school top five, Sumi coming in at 4th and Okamoto at 5th.

Measuring Marathon Courses by Bicycle

http://news.searchina.ne.jp/disp.cgi?y=2013&d=0110&f=column_0110_034.shtml translated by Brett Larner The full marathon is a sport where you compete over 42.195 km, but how do they go about measuring that distance?  Today we're going to look a little bit at how they go about certifying the distance of a marathon. The reality is that major international marathons use a bicycle to measure the distance.  This rule is an international standard, and the same method of measurement is used everywhere.  It was put into place in 1986.  In order to ensure that the same method is used everywhere, a bicycle that meets IAAF specifications must be used for measurement. In the case of Japan's major marathons, to be certain that the distance is correct a provisional measurement is first made.  Before the course is certified using a bicycle the course is measured using a 50 m-long length of wire to determine that it is in fact 42.195 km.  When a bicycle is u...
