Runners follow an out-and-back course for the half marathon that starts just off Wilson Street on the west side of the Fox River. From there, the course takes runners up and down the Fox River, then through historic Batavia before returning to the Fox River Trail and heading back to the finish line. Most of the course is flat, except for some brief hills while heading away from the river (and of course, back toward the river downhill).
