Chicago Half Marathon
Chicago Half Marathon is a flat half marathon in Chicago, USA, held each September. A flat out-and-back from Jackson Park by the Museum of Science and Industry, running north on Lake Shore Drive to a Burnham Park turnaround and back. Late-September mornings, typically mild, around 12-20C. On a course as flat as Chicago Half Marathon, even splits are everything; the classic mistake is banking time in the first third.
