Noční běh Rusava is a night race held at the Rusava Ski Resort in the Hostýnské vrchy mountains of Czechia. The primary event is a 12-hour lap race where runners begin in the evening and continue until morning, aiming to complete the most loops possible. A 5 km option is also available, consisting of one lap on the same basic course.
The course follows the ski slope and surrounding forests of Rusava, making the race focused on repeated night running over hilly terrain rather than a point-to-point course. Participants can enter the 12-hour race as individuals or as relay teams of various sizes. Each runner receives a start number and a unique finisher medal. The short race concludes shortly after its evening start, while the main event proceeds through the night.
