The Ostrava City Marathon is a September road race in Ostrava, a Czech city known for its mining and industrial past. Organizers state it is the oldest marathon in the Czech Republic, tracing its origins to 1954. The current event is part of a city-center running festival that includes a half marathon, a quarter marathon, and the full 42.2 km race.
The route is designed to showcase three aspects of Ostrava: its historic streets, its industrial areas, and its green spaces. The race attracts serious runners and those seeking a festival atmosphere, with participants coming from across the Czech Republic and Europe. The race has had notable historical variations: it was occasionally shortened to 25 km, halted for several years following the death of its first organizer, and later hosted the national championship five times. The contemporary event features music and charity drives, including a MiniMarathon supporting a charitable cause.
