BIWA100ウルトラウォーク is a long-distance walking event set around Lake Biwa, featuring a 100km course starting in Nagahama and finishing at Otsu Port.
What this race demands
This 100 km long-distance walking event around Lake Biwa demands exceptional muscular endurance and multi-hour physical durability to cover the massive distance on foot.
Distance durability
Covering a continuous 100 km on foot requires sustained cardiovascular stamina and the structural resilience to withstand hours of repetitive impact.
Pacing control
Managing energy output carefully from the start in Nagahama to the finish at Otsu Port is essential to prevent premature fatigue over the ultra-distance.
A sustained effort of this extreme duration requires consistent carbohydrate intake of 60 to 90 grams per hour to maintain energy levels and delay depletion.
