The Silesia Marathon is a 42.195 km road race in Poland that passes through three Silesian cities: Katowice, Siemianowice Slaskie, and Myslowice. The organizer states it is the only marathon in Poland and Europe routed through three cities, and it is the largest running event in Silesia and one of Poland's larger marathons.
The route holds an international certificate. The event also features a half marathon, included since 2009. Children's and youth races are held alongside the adult distances, making the weekend inclusive for more than just marathoners. The setting is urban Silesia, a region with industrial centers, historic architecture, and a long past evident in structures ranging from medieval fortresses to Baroque cathedrals.
