Chicago Half Marathon Pace Calculator & Race Plan
The Chicago Half is a flat out-and-back along Lake Shore Drive starting from Jackson Park near the Museum of Science and Industry. Only about 120 feet of total gain. The lakefront course is exposed to wind off Lake Michigan.
September in Chicago is usually good for running. Our model adjusts for the flat terrain and potential lakefront wind.
