Kiyama and Murakami Making International Debuts at United Airlines NYC Half

Since the start of JRN's collegiate development program in 2012, a partnership between the New York Road Runners and the Ageo City Half Marathon that brings two of the top male university half marathoners in the country to the United Airlines NYC Half every year, a total of 25 athletes have made the trip. For most of them it's been their first time racing outside Japan. 10 of the 25 have been from Komazawa University, including 4 of the 5 fastest times and 4 of the 5 best placings. Kenta Murayama's 1:00:57 for 5th in 2017 leads both lists and still stands as the fastest half marathon ever run by a Japanese man on U.S. soil.

This year two more Komazawa runners are in New York as numbers 24 and 25, Yudai Kiyama and Hibiki Murakami. At Ageo last November Kiyama and Murakami ran PBs of 1:01:59 and 1:02:04 for 2nd and 4th overall to pick up invites to the NYC Half. A 3rd-year, Kiyama was a national-level 1500 m runner in high school. At Komazawa he struggled to make its starting roster for the 3-race ekiden season, making only the 10-man Hakone Ekiden squad his 2nd year in 2024, where he was 12th on the downhill Sixth Stage.

This past season he missed the Izumo Ekiden and National University Ekiden teams again, but his Ageo performance marked a breakthrough that was enough to have Komazawa head coach Atsushi Fujita give him the responsibility of handling the important First Stage at Hakone. He ran well, leading the chase pack behind breakaway leader Shunsuke Yoshii of Chuo University and showing his roots as a 1500 m runner with a fast kick that put him 2nd behind Yoshii. A month later he made a massive breakthrough at the Marugame Half Marathon, running as high in the field as 7th in a race where the top 4 all broke 60 minutes, dropping to 15th by 20 km, but coming back with the fastest close in the field to retake 10th.

A 2nd-year, Murakami's standout performance in high school was a win on the 2021 National High School Ekiden's Seventh Stage where he anchored Sera H.S. to the national title. Like Kiyama he didn't make Komazawa's starting roster for any of the 3 ekidens his first year, but after missing Izumo last fall he made his debut 2 weeks before Ageo with a 5th-place run on the National University Ekiden's Fifth Stage. His Ageo time earned him a place on one of Hakone's 2 longest legs, the 23.1 km Ninth Stage, where he was 5th again. Marugame was good to Murakami too as he ran a new PB of 1:01:46.

1:00:32 makes Kiyama the fastest Japanese collegiate runner ever to line up in New York, where he is ranked 5th in the field. Murakami is the 3rd-fastest ever behind Kiyama and Murayama. With other alumni of the program like Yuta Shitara and Akira Akasaki having gone on to break national records and make single-digit placings at the Olympics, good runs in New York would mark Kiyama and Murakami as top people to watch in the next generation of Japanese distance runners. Streaming of the United Airlines NYC Half starts at 7:00 a.m. local time Sunday.

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.

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...
