Official event pageWhat this race demands
This marathon requires sustained pacing over the full 42.2-kilometer distance from Takaoka to Toyama. Athletes must manage muscular fatigue throughout a standard road running format.
Aerobic Endurance
The 42.2-kilometer marathon distance requires a highly developed aerobic energy system and efficient pacing to maintain forward motion over several hours.
Impact Durability
Running continuously on paved surfaces for the duration of the event places repeated loading stress on the lower limbs, requiring specific structural preparation.
A target of 60 to 90 grams of carbohydrates per hour is recommended to sustain energy levels across the marathon duration.
