Like the full marathon and 5K, the course for the half marathon starts and finishes at the Norwalk Village Park on State Highway 71. From there, runners follow the route north up and out of the center of town out along the Elroy Sparta State Trail, and encounter what are perhaps the course’s most significant hills in the first four miles of the race. From the starting elevation of just over 1,000 feet above sea level, the course reaches nearly 1,400 feet by the time runners reach mile 4.
