Tracing its roots back to 1954, the Ostrava City Marathon is Czechia’s most enduring city road race, celebrated for blending competitive endurance running with local history, culture, and charity. Runners can choose from multiple distances—including marathon (42.2 km), half marathon (21.1 km), 10 km, 36 km relay (6 × 6 km), and a Mini Marathon (approx. 4 km)—all set along a flat and fast urban course that weaves through Ostrava’s industrial heritage and its revitalized green spaces. The race weekend doubles as a festival, offering live music, charity initiatives like the Mini Marathon, and atmosphere-rich start and finish areas at Masarykovo náměstí.
