Course records, Swedish national record set at Ageo City Half Marathon
Conditions were perfect for records to fall at the Japanese race

It was a day of records at the 31st Ageo City Half Marathon in Japan today, with both men’s and women’s course records falling, a new Swedish national record (by 20 seconds) set by David Nilsson, and multiple personal bests achieved, in a race that seems to get faster every year. According to Japan Running News, which refers to this race as “the world’s greatest half-marathon,” four men ran under 62 minutes. 2018 Boston Marathon champion Yuki Kawauchi and Japanese national marathon record-holder Yuta Shitara were also among the runners.

Men's and women's CR, a Swedish NR, 4 men under 62 minutes, 18 under 63 minutes. Every year it seems like the question is how much further can the Ageo City Half Marathon go? The answer still seems to be more. More further. https://t.co/uXgikwlunF pic.twitter.com/Ak6gb2IYhW

The top two Japanese collegiate finishers are invited to the next running of the New York half-marathon. Nakayama, of Chuo University, and Genki Kaneko of Josai University received their invitation from Shitara, who was the first Japanese university runner to be invited, back in 2012.
Kawauchi, who has had a number of disappointing times in recent months, finished 14th, with his career third-fastest time of 1:02:49. He and Shitara will square off at the Fukuoka Marathon on December 2.
