The conditions were bad enough that 3 runners were taken to the hospital with heatstroke and world champion Haruki Okayama had to drop out mid-race, but that didn’t stop Hong Kong’s Kok Wai Tse from running strong over the 2nd half of the race to come from behind with an excellent 6:28:39 for the win.
At halfway Tse was almost 2 minutes behind a lead group that included Hideaki Yamauchi and Hideo Nojo, but when they faded in the heat Tse was there to take over. He ultimately finished over 13 minutes ahead of 2nd-place Shion Oe, who likewise had a more conservative start and spent most of the race with eventual 3rd-placer Naoki Matsuo. Yamauchi was ultimately 4th in 6:47:32, splitting 3:07:39/3:39:53, with Nojo 5th in 6:49:37 with even more painful splits of 3:07:30/3:42:07.
