Młode Głowy — because every run matters

Each of the 1000 marathons is also a run for foundation Młode Głowy (Martyna Wojciechowska) — supporting the mental health of young people in Poland. Running and the commemorative race number are free for everyone. If you support the foundation with at least €25, you will receive a commemorative finisher medal right there after the run.
