Fox Valley 20M
Race Day Weather
Warm start, moderate wind, rain likely, high humidity
Starting at 67°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Moderate winds around 14mph may affect pacing on open sections of the course. Rain is likely — waterproof your phone and bib, and consider a disposable poncho for the corral. High humidity (95%) will make it harder to cool down through sweat — increase fluid intake accordingly.

Race Info
The Fall Final 20 is a 20-mile race that starts and finishes at Mt. St. Mary Park in St. Charles. It follows the Fox River south through Geneva and Batavia to a turnaround near North Aurora, then returns along the opposite bank on town streets and river paths. The course is gentle and shaded, with a small roller near mile 10, and it is used by many runners as a long training run before a fall marathon.
