Official event pageWhat this race demands
UltraKotlina demands exceptional mountain running endurance to cover 142 kilometers and 5541 meters of elevation gain through challenging terrain in the Karkonosze range. Athletes must sustain output over a continuous ultra-distance effort in an October mountain environment.
Continuous climbing capacity
Accumulating 5541 meters of elevation gain across a 142 kilometer distance requires sustained power on steep ascents and muscular resilience to protect against fatigue.
Long-distance durability
Covering 142 kilometers demands meticulous pacing and physiological efficiency to maintain forward motion through significant cumulative fatigue.
Descent resilience
Navigating extensive mountain descents following substantial climbing tests eccentric leg strength and joint durability over many hours of racing.
October thermal management
An October event in Szklarska Poręba requires preparedness for cold mountain conditions, rapid weather shifts, and temperature regulation during extended hours of movement.
Given the extended duration of this ultra-distance event, athletes should consume 60 to 90 grams of carbohydrates per hour to maintain energy availability throughout the race.
