The 1978 Chicago Marathon (also known as the Mayor Daley Marathon)[1] was the second running of the annual marathon race in Chicago, United States and was held on September 24. The elite men's and women's races were won by Americans Mark Stanforth (2:19:20) and Lynae Larson (2:59:25). The race was run in temperatures at times above 80 °F (27 °C), which caused hundreds of competitors to need medical attention.
