Japanese National Team for Cali 22 World U20 Championships

The same day most of Japan's team from the Oregon 22 World Championships made it back home, the Cali 22 World U20 Championships team took off from Tokyo ahead of next week's meet. 9 women representing 5 universities and 3 high schools across 6 events and 25 men from 17 universities and 3 high schools across 15 events are entered. But if the numbers in Eugene were anything to go by it's likely the number of them who make it to the starting line will be smaller.

The women are surprisingly absent from the 3000 m, usually an area of strength for them, but the women's team does include Moe Matsuoka (Chuo Univ.), 4th-fastest U20 worldwide in the 400 mH this year, 10000 mRW top 2-ranked Ai Oyama (Kagoshima Joshi H.S.) and Ayane Yanai (Ritsumeikan Univ.), and 2022 worldwide #5 and #6 Momoko Tsuji (Kyushu Kyoritsu Univ.) and Aoi Murakami (Nittai Univ.) in the javelin throw.

Notable names among the men's entries include Oregon 4x100 m team member and worldwide #6 junior Hiroki Yanagita (Toyo Univ.) in the 100 m and 4x100 m, Keita Sato (Komazawa Univ.) in the 3000 m and 5000 m, the H.S. national record holder in both events and U20 NR holder in the 5000 m, 110 mH U20 world #9 Ryona Manago (Fukuoka Univ.), 10000 mRW #2 and #3 Shotaro Shimoike (Kagoshima Kogyo H.S.) and Riku Oie (Juntendo Univ.), and long jump #9 Nozomi Watanabe (Tsukuba Univ.).

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...

The Tokyo Marathon will be her last race. At Nagano Higashi H.S. Hosoda ran in the National High School Ekiden her 2nd and 3rd years.
