Nojo and Mochizuki Take Lake Saroma 100 km Titles

by Brett Larner
complete results coming shortly

Sunny skies and warm temperatures greeted the 29th running of the world's fastest ultra, Hokkaido's Lake Saroma 50 km and 100 km Ultramarathon.  Predicted temperatures over 25C meant probable slow times on the course that hosts both the men's and women's 100 km world records, but that did not stop defending men's 100 km winner Hideo Nojo (New Balance) from going for it.  An opening split of 36:03 for the first 10 km put him right on the cusp being on track to break 6 hours, but while that was clearly not going to be sustainable Nojo pushed on ahead of Takahiro Sunada's 6:13:33 world record pace until nearly halfway before the heat got the better of him.  Slowing to close to 45 minutes per 10 km by 70 km, Nojo rallied late in the race and went back under 40 minutes for the final 10 km to take the win in 6:40:15, three minutes slower than his winning time last year but a world lead by seven and a half minutes.

Women's winner Chiyuki Mochizuki (Canon AC Kyushu), the 2012 and 2013 Lake Saroma 50 km winner, started more conservatively in her 100 km debut, going out at 7:57 pace for the first 10 km before picking it up.  Like Nojo she slowed after halfway, but not long after 60 km she stabilized to just over 49:00 per 10 km, a pace she held all the way to her 7:55:09 finish.  Based on the strength of their performances, both Mochizuki and Nojo will likely lead the Japanese team for November's 100 km World Championships in Doha, Qatar.

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...
