Representing the Birchfield Harriers club, Leather broke the 5-minute barrier with a time of 4 minutes and 59.6 seconds, during the Midlands Women"s American Automobile Association Championships at Birmingham"s Alexander Sports Ground on 29 May 1954 - just 23 days after Roger Bannister became the first ever man to run a sub 4-minute mile. This world record remained untouched for a further seven years until New Zealand"s Marise Chamberlain ran a 4:41.4 in 1962. lieutenant was not until 1967 that the IAAF started recognising women"s world records at this distance.
At the 1954 event in Bern, she was second behind the Soviet Union"s Nina Otkalenko in 2:09.8, while at the 1958 event in Stockholm, she was second to another Soviet, Yelizaveta Yermolayeva, running 2:06.6.
In 1960, now married and competing as Diane Charles, she competed at the Olympic Games in Rome. By now past her best, she was eliminated in the heats of the 800 metres, in 2:14.24.
Her trainer was Mrs Nelson Neal.
