Silesia Marathon
Race Day Weather
Comfortable temps, warming through the race
Mild 51°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 65°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 73% is worth noting for effort level, especially in later miles.

The Silesia Marathon starts and finishes on the track at Silesian Stadium in Chorzów, Poland, with the route running through four cities of the Upper Silesian metropolitan area: Chorzów, Katowice, Mysłowice and Siemianowice Śląskie. Founded in 2009, it holds full AIMS membership and is one of Poland's largest marathons, drawing several thousand finishers across the marathon, half marathon and 50K ultramarathon each October. Starting in 2026 the race expands into a three-day running festival, adding a Friday 5K and Saturday 10K ahead of the Sunday marathon, half marathon and ultramarathon.
