Official event pageWhat this race demands
This extreme non-competitive walking event requires covering a 143 km mountain loop within a strict 48-hour limit.
Continuous endurance
Traversing a 143 km distance requires sustained forward motion over many consecutive hours, testing aerobic capacity and pacing strategy.
Mountain terrain
Crossing four mountain ranges surrounding the Jelenia Góra Valley demands physical resilience against significant cumulative elevation changes and rugged paths.
Sleep and fatigue management
Operating within a 48-hour limit forces athletes to manage sleep deprivation, nighttime navigation, and fatigue accumulation across multiple days.
Given the multi-day duration, athletes should maintain a consistent carbohydrate intake of 30 to 60 grams per hour alongside adequate hydration to sustain energy levels.
