Official event pageWhat this race demands
This 70 km trail running race demands sustained climbing and descent capability across 4,700 meters of elevation gain on rugged single-track mountain paths.
Vertical Endurance
Accumulating 4,700 meters of elevation gain over a 70 km distance requires continuous management of muscular fatigue during prolonged ascents and descents.
Single-Track Efficiency
With over 80 percent of the course consisting of single-track mountain paths, athletes must maintain steady pacing and technical focus on narrow terrain.
November Conditions
Running in November in Koshu, Japan introduces cooler seasonal temperatures that require appropriate layering and thermal management over the course of the event.
Given the substantial duration of a 70 km mountain trail race, athletes should consume 60 to 90 grams of carbohydrates per hour to sustain energy levels.
Estimated finish times
