Runners follow a long, out-and-back route that starts and finishes on Highway 83 near Memorial Park in Palos Heights, and follows a mostly east-west direction out from and back into town. Much of the race takes runners along the edges of the nature preserves and forests that border Calumet Sag Road (which serves as the course for most of the race) and the Saganashkee Slough Woods just south of Chicago.
