Official event pageWhat this race demands
This 100-kilometer walking event requires sustained forward progression over an ultra-endurance distance along the historic Nagasaki Kaido route.
Ultra Distance
Covering 100 kilometers demands exceptional muscular endurance and tissue durability to withstand hours of continuous impact on foot.
Pacing Discipline
Sustaining locomotion over a full-day effort requires strict control of early intensity to prevent premature fatigue before reaching Kokura.
Given the duration of a 100 km walk will greatly exceed 2.5 hours, athletes should consume 30 to 60 grams of carbohydrates per hour to maintain energy levels.
