Silesia Marathon
Race Day Weather
Cool start, gradual warming trend
Runners will face a temperature rise from 47°F at the start to 60°F by the finish, with average humidity at 74%. Wind will be a factor, starting with crosswinds and shifting to headwinds in several sections, particularly Miles 5, 7, and 17. Runners should adjust their pacing strategies for tougher segments by conserving energy early and taking advantage of tailwinds between Miles 8-9 and 19-20.
