Kawauchi Wins 7th-Straight Okinoshima 50 km

Running the Okinoshima 50 km Ultramarathon on his late father's home island of Oki for the eighth year in a row, Yuki Kawauchi (Saitama Pref. Gov't) ran 2:52:55 to win it for the seventh straight time. Starting strong on the relatively flat first 10 km where he clocked 33:26, low-2:47 pace, Kawauchi slowed to just over 2:50 pace on the course's toughest hills between 10 and 30 km. A sub-2:50 was still in range at that point, but over the last 20 km he faded further to finish in the second-slowest of his Okinoshima wins.



The day before the race Kawauchi paced children in Okinoshima's kids' run. Following that he greeted participants and local supporters at an expo event where he was hailed onstage as the Boston Marathon winner. As per his usual routine, his next race will be the July 1 Gold Coast Marathon in Australia.

Kauwauchi could easily be the first to break 2 hours in the marathon. He has the endurance needed, but his stride is not completely efficient. For instance, he bounces up and down 3" like most Western marathoners. But East Africans bounce only 2". We can reduce bounce to 1/2", which means he will be doing 1/6th of the work he does now. In addition, his stride angle (max opening between front and trailing thigh) is only 84 and 80 degrees. We can easily increase that to 100 degrees, which means he will be covering 32-40% more ground with each stride. He has been successful in part because he has little cross-over (6 degrees rt., 3 degrees left)and overstride (0 degees and 7 degrees), which protect his legs from being over-stressed when he runs. We can correct these problems in a few weeks (in addition to increasing his chest expansion to take in more oxygen) so he can set the record at Chicago. Our athletes have won 44 Gold Medals and have set 11 World Records.

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...

Nat'l University Ekiden Updates Here

Looks like I just went over my update limit on Twitter - sorry, it's the first time I've tried to use it for this. I'll look for another option next time. In the meantime I'll add updates to the comments below. Not sure if that has a max too but I guess we'll find out. Update: Part one of the Nationals commentary can be found here .
