Cancelled Olympic marathons - Tokyo / Helsinki 1940
Tokyo / Helsinki 1940 - The anticipated 1940 Summer Olympics, which were to be officially known as Games of the XII Olympiad and originally programmed to be celebrated between September 21 and October 6, 1940 in Tokyo, Japan, were cancelled due to World War II. The Games were retracted from Tokyo by the IOC due to the outbreak of the Second Sino-Japanese War in 1937. They were awarded to the runner-up Helsinki, Finland, and were scheduled to be celebrated between July 20 to August 4, 1940. When World War II broke out, and the Soviet Union attacked Finland, the Summer Games were cancelled indefinitely.
