NN Night Run Ostrava is a stage of the NN Night Run evening race series; in 2026 the Ostrava race opened the season on 11 April with around 1,800 runners. You run after dark through central Ostrava, with music and lighting along the route, over 5 or 10 km — distances within reach of beginners and seasoned runners alike. It is more night party than time trial: many come in groups and bright outfits. The vibe is young and energetic, fitting a city whose Stodolní Street never sleeps. Ostrava offers Dolní Vítkovice with its blast furnaces and concerts, the New Town Hall lookout tower and Silesian Ostrava Castle.
