100 metres, Men

Date	30 – 31 July 1948
Status	Olympic
Location	Empire Stadium, Wembley, London
Participants	63 from 33 countries
Olympic Record	10.2w / Jesse Owens USA / 2 August 1936 / Details

The fastest sprinters in the world in 1948 were felt to be Mel Patton of the USA, and Lloyd LaBeach of Panama, who became his nation’s first Olympic athlete ever in London. They had raced several times in 1947 and early 1948, basically splitting the races, as there was little to choose between them. Another top sprinter was Barney Ewell, but he had been at his best during the war years and was felt to be slightly past his prime. One athlete who would not compete in London was Hal Davis, who would have been favored in either 1940 or 1944 if the Olympics had not been lost to the war.

An unusual thing happened at the US Olympic Trials. The heavy favorite in the high hurdles was Harrison Dillard, who had not lost a hurdle race in several years, but he hit a hurdle in the final of the Trials and did not finish. Fortunately for him, he had also entered the 100 metres and made the team in that event, behind Patton and Ewell. In the Olympic final, Patton got off to a disastrous start and was not a factor. Dillard led from start to finish, with Ewell closing quickly to get the silver medal, and LaBeach in third.
