Fox Valley Marathon

Course highlights

The half marathon, like the full marathon and the 20-mile race, follows an out-and-back course that starts and finishes in St. Charles near the northern edge of Mt. St. Mary Park, a 29-acre park filled with paved running and walking trails, children’s playground areas and sculpture throughout, on the western side of the river.

From there, runners follow the loop course all the way south to Batavia and approaching Batavia Township, passing through local parks like Wheeler Park and the Glenwood County Forest Preserve along the way.

The first two miles or so of the half marathon take runners along city streets, taking them from the starting line along Geneva Road and River Lane before crossing the bridge at State Street and then turning runners onto the Algonquin to Aurora section of the Fox River Trail.

The course keeps runners on the trail, which is paved, for the next three miles until they reach the Batavia Museum Depot near Houston Street, where they rejoin the city streets briefly and then head back onto the path for the stretch that takes them southward to the turnaround point on the Illinois Prairie Path.

This stretch also features the biggest uphill stretch of the race, but not to worry — the few changes in elevation are very minor throughout the course, thanks largely to its location along the banks of the Fox River. Once they make the turn and begin heading north, runners head back along the path they’ve just run for roughly the next two miles before splitting off just before reaching where the trail nears Batavia’s Laurel Street.

They then head north mostly along the eastern side of the river, before crossing the bridge at Illinois Street to head over to the finish line where they started.
