What this race demands
This fifty-kilometer hike requires sustaining forward motion and structural durability for up to twelve hours over mountainous terrain.
Extended Duration
Completing fifty kilometers within the twelve-hour time limit demands continuous pacing and cardiovascular endurance over a prolonged period.
Muscular Durability
Navigating the numerous meters of elevation change across mountainous terrain creates substantial cumulative eccentric load on the lower limbs.
Given the duration of up to twelve hours, athletes should consume 60 to 90 grams of carbohydrates per hour to sustain energy output and prevent severe glycogen depletion.
Estimated finish times
Estimates by level, not promises. Your own number depends on your fitness on the day.
