Bieg Miki Run 2026

Bieg Miki Run is a cross-country obstacle race on a former military training ground in Piła, Poland. Adults run 7 km with roughly 50 obstacles, while children get a shorter 2 km route with about 25 obstacles. The event is built around mud, uneven ground, natural barriers, and man-made obstacles rather than road racing, so it asks for strength and grit as much as running speed. The field is capped at 370 participants, with wave starts and a separate elite wave for faster or more competitive adults. Adult runners are timed electronically with a returnable chip in the start package, while children run without timing. Entry is handled as a donation: the money goes toward buying a bionic hand prosthesis, with different donation amounts for children, adults, and elite runners.
