Course Preview Runs

No Surprises on Race Day!

Throughout the summer, we will be hosting group training runs on the trail where the Fox Valley Marathon Races take place. Come on out, get a glimpse of what you will be running on race day, meet fellow runners, and knock out a long distance run all at once!



Due to runner feedback and knowing the importance of hydration during the warm training, all on course hydration stops for our course test drives will be at park district water fountains. The primary reason for this is the ability for our runners to freely fill their bottles and to ensure that water is always available for you! We encourage you to carry your preferred energy drink.

View our Fox River Trail Water Guide for fountain locations along the East and West side trails.  We strongly advise reviewing the maps and acquainting yourself with water fountain locations. We’ll have fluids for you at our main tent at the start/finish.

Of course this doesn’t apply to race day where you’ll continue to enjoy our abundant aid stations fully stocked with water and Endurance Gatorade as well as our two Clif Energy Zones!

See the table below for the preview run schedule and scroll down further to see maps for each day’s run.


All runs start at 6:30 AM.

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.
