This was one of the busiest weekends of the year for Japanese marathons, with at least five big races across the country. The fastest was the Kanazawa Marathon with a field of 13,000, with Kenta Fukumura winning for the second year in a row in 2:16:51 and Chifumi Ito running an almost 9-minute PB of 2:34:45 to break the women's course record.

With a field of 25,000 the Yokohama Marathon was the biggest, if not the fastest of the weekend. Rikuto Okubo won the men's race in 2:23:45, with former corporate leaguer Yukari Yasutome winning the women's race in 2:51:53.

Measuring Marathon Courses by Bicycle
