A total of ten preliminary runs were carried out on August 19 (9:30 a.m. local time). The athletes who finished in the first two places qualified for the quarter-finals, which took place on the same day at 3:15 p.m. In each of these four runs, the top three made it to the semi-finals of the following day. In both preliminary rounds, starting from 2 p.m., the first three runners qualified for the final, which started at 4.15 p.m.
Note: The runners qualified for the next round are highlighted in light blue.
Prelims
Failed in the semifinals: world record holder Ted Meredith (USA)
The times run in the final were pretty weak given Ted Meredith's world record of 47.4 s. However, the condition of the track and the fact that the preliminary rounds took place on the same day as the final must be taken into account.
There was nothing left of the superiority of the Americans in the last games - there was only one runner in the final who did not come from the USA. The South African Bevil Rudd was victorious in a cleverly arranged race.
Rudd's victory was the first South African gold medal in this discipline. Nils Engdahl won the first Swedish medal over 400 meters .
