A typhoon was approaching Japan in the days before the race, and the 100 mile started on schedule on Monday evening in rain that fell all night. It cleared on Tuesday morning, earlier than forecast, just as the 110 km set off. Both races ran to their limits: the last of the 323 official 100 mile finishers came in at 32:58:46, 63 of them in the final half hour, and 142 of the 110 km's 452 finishers arrived in its last half hour before 22 hours.
