Status	Olympic
Location	Alberca Olímpica Francisco Márquez, Ciudad de México
Participants	64 from 35 countries

At the US Olympic Trials, Zac Zorn, 1967 Pan American Games silver medalist, had equalled the world record, posting 52.6. Mike Wenden of Australia was considered a long-shot, his best time prior to the Australian trials only 53.7, but he posted the fastest time in the heats and the semi-finals, equalling the Olympic record in the semis. Zorn took the lead at the turn but he had been sick all week in Mexico City, and faded badly on the final lap, finishing last among the finalists. Wenden finished very strongly to win the gold medal over Ken Walsh and Mark Spitz. Fourth place went to Bobby McGregor, the silver medalist from Tokyo who had won the 1966 European Championships.
