National Corporate Women's Ekiden Champion Team to be Stripped of Title After Member Tests Positive

On July 18 it was learned from several sources connected with the situation that a member of the 2017 National Corporate Women's Ekiden champion team Universal Entertainment who left the team at the end of last season tested positive for a banned substance in a doping test carried out at the ekiden. Universal Entertainment won the national championship race, its second-ever title and first in five years. But because the athlete's result will be annulled the team will also be stripped of its title, an unprecedented situation in the ekiden's history.

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.
