Silesia Ultramarathon 2026

The Silesia Ultramarathon is a 50 km road race through cities in Poland’s Silesian region, starting early in October. It is organized by the Silesia Marathon Foundation in Chorzów, with its office at Stadion Śląski, and receives support from the Marshal’s Office of the Silesian Voivodeship. Katowice, Mysłowice, Siemianowice Śląskie, and Chorzów are partner cities, making this a regional city-to-city ultra, not a mountain or trail race. The route follows urban streets with controlled car traffic, and the distance is certified by PZLA and World Athletics. Runners will find aid stations approximately every 5 km, with additional water points between them. This is important on a 50 km road course where pacing and consistent fueling are key challenges. Entrants must be adults, confirm their fitness to run, and adhere to instructions from police, municipal guards, and course staff.
