Kaźmierz hosts the Półmaraton Doliny Samy, a local race event built around a half marathon and a 10 km run called the Pyrlandzka Dycha. The programme also includes a children's run and Nordic Walking competitions, so the day is not limited to runners chasing the main distance.
The event runs in and around the Samy valley area, with participants finishing in Kaźmierz. It has reached at least its 12th edition, and finishers receive eco-friendly medals along with prizes at the line.
