Race Day Weather
Comfortable temps, big temp swing
Starting at 60°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temps will climb significantly to 78°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. Moderate humidity at 67% is worth noting for effort level, especially in later miles.

Combining small race atmosphere with big race amenities, the Fox Valley Marathon, Half Marathon, and Fall Final 20 are ideal for both veterans looking for a fast race, as well as first timers looking for an uncrowded, supportive, family-friendly race setting. Starting and ending in historic downtown St Charles, IL, the course winds through picturesque Geneva, Batavia, North Aurora, and Aurora to a spectacular finish across the Fox River that can be seen from over a mile away. The course offers fantastic viewing spots for families and supporters, as well as frequent and well positioned aid stations that are staffed by the most supportive volunteer teams of any race you’ve run.
