Athletics at the 1948 Summer Olympics – Men's 800 metres

The competitors all started from a crouch start. In the final, Marcel Hansenne bolted from the blocks to take the lead. The tall Arthur Wint worked his way through the crowd and moved into the marking position by the end of the turn. Mal Whitfield smoothly ran around the crowd, past Wint and Hansenne into the lead. Whitfield kept going, extending his lead to five metres uncontested. Ingvar Bengtsson moved forward to challenge Hansenne, holding the edge through the final turn. Coming off the final turn, Wint ran around both of them and set off in chase of Whitfield. He was able to close down a couple of meters but the gap was too much, Whitfield winning easily. Behind them, Herb Barten ran around the outside of Bengtsson and challenged Hansenne to the line, but Hansenne took the bronze.

This was the 11th appearance of the event, which is one of 12 athletics events to have been held at every Summer Olympics. None of the finalists from the pre-war 1936 Games returned. Noted contenders included Mal Whitfield of the United States, Arthur Wint of Jamaica, Doug Harris of New Zealand, and Marcel Hansenne of France.[1]

Egypt, Iceland, Jamaica, South Korea, and Trinidad and Tobago appeared in the event for the first time. Great Britain and the United States each made their 10th appearance, tied for the most among all nations.

The event used the three-round format introduced in 1912. There were six first-round heats, each with 7 and 8 athletes (before withdrawals); the top four runners in each heat advanced to the semifinals. There were three semifinals with 8 athletes each; the top three runners in each semifinal advanced to the nine-man final.[1][3]
