The 100 km race starts at the Sports Center in the town of Yubetsu in the west of Lake Saroma, takes a course around the Lake Saroma with two main peaks of around 40 meters[3] and finishes at the Sports Center in the Town of Tokoro. Men's 100 km course record is 6:09:14 achieved in 2018 by Nao Kazami, and women's course record is 6:33:11 achieved in 2000 by Tomoe Abe. Both records are current IAU and IAAF 100 km Road world records.[4][5][6] Time limit to finish the 100 km race is 13 hours. Notable athletes who had run the race include Erick Wainaina in 2010 and 2013.

The course' scenic beauty was described as "one of the most beautiful Ultra courses" by Malcolm Campbell, the founder and then president of IAU[7] who visited Saroma in 1994 to announce the start of the race.[8]
