The Oak Brook Half Marathon course starts just a stone’s throw from the race finish line, just above Oak Brook’s Central Park right in the heart of the village area. From there, runners turn right onto Jorie Boulevard and then left onto 31st Street, which they run for a quick stretch before turning left again into the Oak Brook Polo Grounds. The race’s last few miles take runners around Oak Brook Golf Club, along the bike and running path that leads back to Central Park for the finish.
