Competition format The competition used a two-round (heats and final) format. The advancement rule followed the format introduced in 1952. A swimmer's place in the heat was not used to determine advancement; instead, the fastest times from across all heats in a round were used. There were 5 heats of up to 8 swimmers each. The top 8 swimmers advanced to the final. Swim-offs were used as necessary to break ties. This swimming event used backstroke. Because an Olympic-size swimming pool is 50 metres long, this race consisted of four lengths of the pool. Records These were the standing world and Olympic records (in seconds) prior to the 1964 Summer Olympics. The heats saw two swimmers break the Olympic record: Dan Harrigan in heat 2, with 2:02.25, then John Naber in heat 5 with 2:02.01. In the final, Naber broke the world record and the 2-minute barrier, swimming 1:59.19. Peter Rocca, in second-place, was also under the previous world record time. Schedule All times are Eastern Daylight Time (UTC-4) Results Heats Final Naber set a strong pace to start, hitting the 50-metre turn at 27.73—already a full second ahead of Rocca and Harrigan. Naber's second turn, at 100 metres, came at 57.45 (which would have been 5th place in the 100 metre final) and pushed his lead further. In the final 50 metres, Rocca closed the lead somewhat; he finished with what would have been a new world record except that he was still 1.36 seconds behind Naber.
