Race Day Weather
September in the Midwest usually offers perfect weather for a marathon. The average morning temperature hovers near 52 degrees with afternoon highs reaching toward 75 degrees. Weather can sometimes be unpredictable. Runners should be prepared to wear multiple layers, as the weather can vary widely from the start to the finish of the race. We rely on the weather team at WQAD for up to the minute weather updates when making our final contingency plans for race weekend.
