About the Fox Valley Marathon Races

Combining small race atmosphere with big race amenities, the DuPage Medical Group Fox Valley Marathon, Half Marathon, and Fall Final 20 are ideal for both veterans looking for a fast Boston Qualifier 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.
