As part of its measures to deal with the hot conditions expected at the 2020 Tokyo Olympic and Paralympic Games, on Aug. 13 the Tokyo Metropolitan Government conducted an experiment to measure the effects on pavement surface temperature of spraying the road surface with water. Data from the experiments were released to the media.
The experiment was conducted from 4:00 a.m. to 10:00 a.m. along a 120 m section of sidewalk along Uchibori Street in the Imperial Palace's outer gardens in Chiyoda Ward. In the experiment, open-ended tubes used in agricultural work eres placed at the edge of the sidewalk to supply water. Surface temperature readings were taken every 30 minutes for three different experimental scenarios: spraying water beginning at 4:00 a.m.spraying water beginning at 7:00 a.m.not spraying any water
The experiment found that where water had been sprayed, the road surface temperature remained in the 27 to 29˚C range even when the air temperature exceeded 30˚C. Where no wa…
It's been 122 days since the 122nd Boston Marathon. Of what the two exceptional people who won that day accomplished, WilliamShakespeare summed it up better than any other commentator in his Sonnet 122:
Beyond all date, even to eternity; Or at the least, so long as brain and heart Have faculty by nature to subsist; Till each to razed oblivion yield his part Of thee, thy record never can be miss'd.
What else needs to be said? But the other thing that remains from that day is, of course, this:
Worst punditry ever? #Yukipic.twitter.com/AwjeuZDtOt

In the 122 days since Boston this clip has been on my mind a lot. The commentary here by Larry Rawson and Al Trautwig was exceptionally bad, but it wasn't unique to them and highlighted many of the problems with marathon TV broadcasts and especially their hosts and commentators. I'm fortunate to live in Japan where the announcers for the countless marathon live TV broadcas…
Running on the same course where Japan's Takahiro Sunada set the road 100 km world record of 6:13:33 twenty years ago, 2:17:23 marathoner Nao Kazamibested a deep and competitive field to win the Lake Saroma 100 km Ultramarathon in a world record 6:09:14.
Part of a front group of at least five that went through the marathon split in 2:33:36, on pace for 6:04:01, Kazami lost touch with the lead as rivals Koji Hayasaka and Takehiko Gyoba surged just before halfway to open a roughly 30 second lead that lasted until nearly 75 km. But in the last quarter of the race Kazami, a graduate of Hakone Ekiden powerhouse Komazawa University, was the only one who could sustain anything close to the early pace, overtaking Hayasaka and Gyoba before pulling away to open a lead of over 11 minutes. Kazami's mark took more than 4 minutes off the world record, and he also bettered the 100 km track world record of 6:10:20 set in 1978 well before he was born by the late Don Ritchie.
