Overview

The Ultra Silesia Marathon, a 50k road race, distinguishes itself with a cut-off tighter than 98% of its 1013 peer races, requiring runners to maintain a pace faster than 7.2 minutes per kilometre to finish within the 6-hour limit. This leaves less margin than in most 50k events.

The course itself presents 223 metres of elevation gain, which averages 4.5 metres of climb per kilometre. With 301 finishers in 2025, this race has a larger field than 95% of its 2654 peer 50k races.

Organised by the Silesia Marathon Foundation, the event has taken place 7 times since 2019, with the 2026 edition scheduled for October 4. The 180 PLN entry fee gives access to a route that winds through the streets of 4 cities, including Chorzow where the race starts.
