The Muszynianka Poland CUP Puchar Polski MTB XCO UCI is Poland’s national mountain bike cross-country Olympic series, organized by the Polish Cycling Federation. The races hold UCI status and are part of the Polish Cup calendar. Some rounds also function as Eliminacje OOM MTB qualifying events.
A round takes place in Krynica Zdrój, a mountain area near Muszyna. The local foundation Klub Kolarski Agnieszka Skalniak-Żegiestów is the organizer. The competition is divided into junior, under-23 (Orlik), and elite categories for both men and women, allowing developing Polish riders and senior racers to compete in the same MTB XCO program.
