Official event pageWhat this race demands
This extreme mountain ultramarathon demands sustained physiological output and high durability over a massive distance and elevation profile in the Beskids.
Extreme Climbing Volume
Covering 5300 meters of elevation gain over a 101 km route requires exceptional uphill muscular endurance and hiking efficiency on steep mountain terrain.
Ultra-Distance Durability
A 101 km trail running format places immense stress on connective tissue and energy systems, demanding strict pacing and metabolic resilience over many hours of continuous movement.
August Heat Management
Racing in late August requires effective thermoregulation strategies and consistent fluid and electrolyte intake to maintain performance through variable mountain conditions.
Given a duration well exceeding 2.5 hours, athletes should target 60 to 90 grams of carbohydrates per hour through a combination of drinks, gels, and solid foods to sustain output.
Estimated finish times
