Official event pageWhat this race demands
This 100 km ultra walking event on Shodoshima Island requires sustained endurance over a demanding, undulating coastal course.
Ultra Distance Durability
Covering 100 km entirely on foot demands exceptional muscular and cardiovascular endurance, requiring continuous forward movement for many hours.
Undulating Elevation
The 1,400 meters of elevation gain across the course introduces persistent climbing and descending forces that load the lower limbs repeatedly.
Given the extended duration of an ultra walk, athletes should target 30 to 60 grams of carbohydrates per hour to maintain energy levels.
Estimated finish times
Estimates by level, not promises. Your own number depends on your fitness on the day.
