Mordownik is an ultramarathon that can be done on foot or by bike, with orienteering integrated into the race. Participants do not just follow a marked route; each person receives a map and must navigate between control points.
The control card is part of the challenge, as participants punch it to prove they reached the required points. The exact course details vary by route, so the main idea of Mordownik is endurance mixed with map reading rather than a simple point-to-point race.
