In finding the fastest human swimming speed, the actual speeds were rarely stated in any sources. The record times for all the different styles (freestyle, breaststroke, etc.) and race lengths were easy to find so the speed for each of these had to be calculated to find the highest speed.

The fastest speed reached by a human in swimming is 2.29 m/s. This record was set by Tom Jager in a 50 meter race, in a 50 meter swimming pool in Nashville, Tennessee on March 24, 1990, with a time of 21.81 seconds. The record time for the 100 meter in a 50 meter pool was 48.21 seconds, which means that the average speed was only 2.07 m/s. The record times for the 50 meter and 100 meter races in 25 meter pools were both longer, respectively. A previous speed record set in 1971 by David Holmes Edgar was 5.05 mph (2.26 m/s), slightly less than the speed of Jager in his record setting race. Mark Spitz had an average of 4.367 mph (1.95 m/s) in setting the 100m record in 1972.

The average speed is what is calculated form 50 meter races, but the speed over a shorter distance may be greater. This information, however, is probably not documented and if so, is not readily available.
