The Ultramaraton Chudy Wawrzyniec features challenging mountain runs with two main distances: approximately 80 km with an elevation gain of 3400 m, and slightly over 50 km with 2100 m of ascent. This linear course demands technical skills and endurance, with a time limit of 16 hours to complete the route, which unfolds in the scenic Beskid Żywiecki. Set to attract up to 800 runners, the race begins in Rajcza and may require adjustments to the starting time to align with local train schedules.
