Silesia Marathon
Race Day Weather
Cool start, warming finish
Runners will face a temperature rise from 36°F at the start to 69°F by the finish, with mild humidity at 57%. Light winds at 8 mph will create a crosswind effect in the early miles and headwinds around Mile 7 and 17, challenging runners' pacing. It is advisable to start conservatively and stay hydrated as temperatures rise, especially in the second half of the race.

Race Info
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.
