Official event pageWhat this race demands
Bieg Rzeźnika demands sustained effort over an 80 km mountain trail running and hiking course in the Bieszczady mountains, completed in pairs.
Ultra Distance
Covering 80 km requires exceptional aerobic endurance and muscular resilience to sustain forward motion over many hours.
Mountain Terrain
The Bieszczady mountain setting requires technical trail running and hiking skills to handle variable off-road conditions.
Team Coordination
Starting and running the event in pairs demands synchronized pacing, shared nutrition strategies, and mutual physical and mental support.
Due to the extended duration well beyond 2.5 hours, athletes should target 60 to 90 grams of carbohydrates per hour to maintain energy levels throughout the 80 km distance.
