1,500 metres Freestyle, Men

Date	5 – 7 August 1948
Status	Olympic
Location	Wembley Arena, Wembley, London
Participants	39 from 21 countries

In 1938, Japan’s Tomikatsu Amano had become the first man to break 19 minutes for the 1,500 metres, and his example had been matched by a younger generation of Japanese swimmers. However, since Japan was not invited to the 1948 Olympics, the mantle of favorite for this event fell on France’s Alex Jany. The Frenchman performed poorly in his other events and, after the British food had proved too much for his stomach, was too ill to compete in the 1500m. This left the way clear for the 17 year old American schoolboy Jimmy McLane, and the previously unconsidered Australian John Marshall to battle for the gold.

McLane started well and maintained a lead for the first thousand metres. With 500m to go, Marshall made his challenge, and the two men swam stroke for stroke for the next two lengths of the pool. The Australian’s challenge faded and the more technically gifted McLane swam away to become the first American to win the event since Antwerp.
