Miyawaki 1:00:53 CR in Debut, Shitara 1:01:48 PB in New York - Weekend Half-Marathon Results

by Brett Larner

20-year-olds dominated the Japanese half-marathon news this weekend. 20-year-old Olympic 10000 m squad favorite Chihiro Miyawaki (Team Toyota) set a course record of 1:00:53 in his half-marathon at the National Corporate Half-Marathon Championships, outkicking Kenyan Jacob Wanjuki (Team Aichi Seiko) on the final lap of the track after dueling with the talented Masato Kihara (Team Kanebo) throughout the race. Miyawaki's time was the third-fastest ever by a Japanese man on an unaided course, with Kihara's 1:01:15 PB landing him at all-time #8. Tamagawa Univ. grad Tomomi Tanaka (Team Daiichi Seimei) won the women's race in 1:09:47, the first sub-70 by a Japanese woman this year, while past 1500 m national champion Mika Yoshikawa (Team Panasonic) won the women's 10 km in 32:59 by a second over Kenyan Grace Kimanzi (Team Starts).

A few hours and half a world away 20-year-old Yuta Shitara (Toyo Univ.), runner up at last year's Ageo City Half-Marathon, ran a PB of 1:01:48 to take 14th at the New York City Half-Marathon, dropping 2009 World Half Marathon Championships bronze medalist Dathan Ritzenhein (U.S.A.) with 1 km to go after splitting two seconds faster than his track 10000 m PB on the hills of the course's first 10 km. Shitara's mark was the fastest-ever by a Japanese man on U.S. soil. His teammate Kento Otsu (Toyo Univ.), also 20, was 25th in 1:03:15 in his international debut. Both Shitara and Otsu were invited to New York as part of a relationship set up by JRN between the NYC Half and Ageo to help give top Japanese collegiates international experience at their best distance early in their careers.

University women were also in the news as little-known Ayame Takaki (Meijo Univ.) ran a strong 1:11:10 to win the National University Women's Half-Marathon Championships in Matsue. Takaki won by more than a minute over a small chase pack. Maki Arai (Team Uniqlo) took the 10 km in 33:46.

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. During her 3rd year at Nittai University she won both the 5000 m and 10000 m at the Kanto Region University Track and Field Championships, going on to win the bronze medal in the 10000 m at the World University Games in her 4th year at Nittai. After graduating she joined the Daihatsu corporate team, debuting at the 2019 Nagoya Women's Marathon in 2:29:27. 2 years later she transferred to Edion. She qualified for the Paris Olympics marathon trials at the 2022 Nagoya Women's Marathon and finished 3rd in the trials in the fall of 2023, but was later bumped down to Olympic alternate after another athlete ran a faster time. Instead of the Olympics, Hosoda ran the 2024 Ber...
