Keny and Maruyama Lead Beppu-Oita Mainichi Marathon Field

by Brett Larner

With just over two weeks to go the organizers of the Beppu-Oita Mainichi Marathon have announced their elite field for their 66th running on Feb. 5. Kenyan Felix Keny fronts the field, a former 2:07 man with a best recent time of 2:09:04 in Hamburg three years ago.  Likewise, #2-ranked international Dereje Debele of Ethiopia has run 2:07 in years past, but in the last three years hasn't broken 2:10 with his 2:10:31 at the 2015 Mumbai Marathon his best recent credential.  American Jeffrey Eggleston completes the front of the overseas contingent with a 2:10:52 runner-up finish at the 2014 Gold Coast Airport Marathon.

Beppu-Oita Mainichi factors into the complicated selection process for the 2017 London World Championships men's marathon team with a slot potentially available to a Japanese winner.  The best chance of seeing that happen comes from the talented Fumihiro Maruyama of the 2017 New Year Ekiden national champion Asahi Kasei team, Maruyama having debuted in style in 2:09:39 at last year's Lake Biwa Mainichi Marathon with an overly aggressive surge near 30 km.  If he learned from that mistake and is near the same fitness he may become the first Japanese man to win Beppu-Oita since Yuki Kawauchi in 2013.

The runner-up in that race, Kentaro Nakamoto (Yasukawa Denki), is one of the best Japanese marathoners of the modern era but has been in decline since finishing 5th at the 2013 Moscow World Championships.  A comeback run would make him a definite contender.  Likewise for Maruyama's sub-2:10 teammate Tomoya Adachi (Asahi Kasei), a local who won Beppu-Oita in 2008 in his marathon debut.  Despite only having a 2:12:48 best, Ryo Kiname (MHPS) is a solid threat after winning August's Hokkaido Marathon.

Potential darkhorses include the independent Aritaka Kajiwara, who trains with three-time Hakone Ekiden champion Aoyama Gakuin University, debuting New Year Ekiden Third Stage winner Minato Oishi (Toyota) and his teammate Tsubasa Hayakawa (Toyota), and the Koichi Morishita-coached Kento Otsu (Team Toyota Kyushu), running his second marathon after a failed debut in Hokkaido last year.

The Beppu-Oita Mainichi Marathon will be broadcast live by TBS on Feb. 5 starting at 11:50 a.m. Japan time.  Follow @JRNLive for coverage and live streaming details.

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...
