The Lake Saroma Ultramarathon is an annual 100 km and 50 km Ultramarathon foot road race held in June in the northeastern shore of Hokkaido, Japan since 1987. It is an IAU-labeled official 100 km and 50 km race, and an official JAAF race, and an AIMS (Association of International Marathons)-certified course. Its 1994 event was Asia's first IAU (International Association of Ultrarunners) 100 km World Championship, and its 20th event in 2005 was also held as the IAU 100 km Road World Championship.[1][2]

Course

Location of Lake Saroma in Japan

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 World Athletics 100 km road world records.[4][5][6][7] 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 50 km race starts at the Town of Saroma, finishing at the same place as the 100 km race in the town of Tokoro. Time limit to finish the 50 km race is 8 hours.

The course' scenic beauty was described as "one of the most beautiful Ultra courses" by Malcolm Campbell, the founder and then president of IAU[8] who visited Saroma in 1994 to announce the start of the race.[9]
