The Ultra Hańcza competition takes place in the north-eastern corner of Poland, close to the border with Lithuania, approx. 350 km from Warsaw, in a very hilly area full of lakes and ancient forests. It is a very young postglacial landscape, unique in the scale of the entire Central Europe. The routes run, among others along the deepest lake in Poland. Nature and landscape are protected in a specially created for this purpose Suwałki Landscape Park. The name of the run comes from both Lake Hańcza and the Czarna Hańcza River, which flows from the lake.
