Bieg Tygrysa Zaprawa is a race series held in Orzysz, a town designated in event listings as Poland's Military Capital. Participants can select from three distances: Duża Beczka (over 30 km), Mała Beczka (over 20 km), and Zaprawa (over 12.5 km).
All three races commence in Orzysz, centering the series on a single military-themed host town instead of distinct point-to-point courses. Each distance offers open, women's, men's, and masters categories, catering to both overall competition and age-group rankings.
