Tommie Smith's 1968 Olympic gold medal victory was the fastest recorded fully electronic 200 metre sprint up to that time. Starting on January 1, 1977, the IAAF required fully automatic timing to the hundredth of a second for these events.

12 seconds for the 200 metre equivalent, he is estimated to have run 20.14 for that distance. Tommie Smith ran 20.26 for 220 yards at Provo in 1967. The electronic time was 20.36 seconds, which was the fastest auto time to that date. Henry Carr's winning time at the 1964 Olympics (17 October) was a hand timed 20.3 seconds. The run was not ratified as a world record because Carlos was wearing shoes with 'brush' spikes which did not have sanction as official footwear. John Carlos ran 19.7A seconds (19.92A auto) (1.9 ms wind), at altitude, at the 1968 US Olympic Trials in Echo Summit. The "Time" column indicates the ratified mark the "Wind" column indicates the wind assistance in metres per second, 2.0 m/s the current maximum allowable, a negative indicates the mark was set running into a wind the "Auto" column indicates a fully automatic time that was also recorded in the event when hand-timed marks were used for official records, or which was the basis for the official mark, rounded to the 10th or 100th of a second, depending on the rules then in place.
