Runners start the Naperville Trails Half Marathon course near the equestrian center inside Naperville’s Danada Forest Preserve, and head out onto the crushed limestone trails that wind their way through the preserve, toward the intersection of Butterfield Road and Leask Lane. Once they reach the turnaround, runners then head back along the trails toward the equestrian center, and continue west toward the Arrowhead Country Club and into the nearby Herrick Lake Forest Preserve, where they’ll make a figure-eight-shaped loop and then head back east toward Danada Forest Preserve.
