What this race demands

This 138 km trail running race demands exceptional endurance and resilience to overcome over 8,000 meters of elevation gain in high-altitude mountain terrain.

Massive climbing volume

Accumulating over 8,000 meters of elevation gain across a 138 km distance requires sustained climbing strength and efficient movement on steep ascents and descents.

High-altitude durability

Operating in 2,000-meter alpine environments for an extended duration demands strong cardiovascular capacity and thermal regulation.

Ultra-distance pacing

Completing 138 km necessitates strict energy management and consistent nutritional intake to sustain forward motion over many hours.

Given the exceptionally long duration of this event, athletes should target an intake of 60 to 90 grams of carbohydrates per hour to maintain energy output.
