Men's 400 metres world record progression

The first world record in the 400 m for men (athletics) was recognized by the International Amateur Athletics Federation, now known as World Athletics, in 1912. The IAAF ratified Charles Reidpath's 48.2 s performance set at that year's Stockholm Olympics as a world record, but it also recognized the superior mark over 440 yards (402.336 metres) run by Maxie Long in 1900 as a world record.

Up to and including 2021, World Athletics has ratified 24 outdoor world records in the event.^[1]

The following tables show the world record progression in the men's 400 metres, as ratified by World Athletics.

Indoor

Indoor records are run on a shorter 200 metres track. "y" indicates marks were set over the 440 yards (402.34 m) imperial distance, and an asterisk indicates a record was repeated. All records since Schönlebe's 45.41 in 1986 were ratified by the IAAF.^[2]

(+) plus sign denotes en route time during longer race
"y" denotes time for 440 yards, ratified as a record for this event
"A" indicates that the time was set at altitude.

The "Time" column indicates the ratified mark; 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 of a second, depending on the rules then in place.

Records post-1976

From 1975, the IAAF accepted separate automatically electronically timed records for events up to 400 metres. Starting January 1, 1977, the IAAF required fully automatic timing to the hundredth of a second for these events.^[1]

Lee Evans' 1968 Olympic gold medal victory time of 43.86 was the fastest recorded result to that time.

Time	Athlete	Nationality	Location of race	Date	Duration of record
43.86 A	Lee Evans	United States	Mexico City, Mexico	October 18, 1968^[1]	19 years, 9 months and 30 days
43.29	Butch Reynolds	United States	Zürich, Switzerland	August 17, 1988^[1]	11 years and 9 days
43.18	Michael Johnson	United States	Seville, Spain	August 26, 1999^[1]	16 years, 11 months and 19 days
43.03	Wayde van Niekerk	South Africa	Rio de Janeiro, Brazil	August 14, 2016^[6]	9 years, 2 months and 5 days

For the period when the record automatic time was Lee Evans' mark of 43.86, the progression excluding races run at high altitude (above 1,000 metres) was as follows:

Time	Athlete	Nationality	Location of race	Date	Duration of record
44.95	Lee Evans	United States	Winnipeg, Canada	July 30, 1967	4 years and 2 days
44.60	John Smith	United States	Cali, Colombia^[7]	August 1, 1971	4 years, 11 months and 28 days
44.26	Alberto Juantorena	Cuba	Montreal, Canada	July 29, 1976	10 years, 9 months and 4 days
44.10	Butch Reynolds	United States	Columbus, Ohio, USA	May 3, 1987	1 year, 2 months and 17 days
43.93	Butch Reynolds	United States	Indianapolis, USA	July 20, 1988	28 days

Notes

^ Eric Liddell's 1924 Olympic Games victory was initially ratified as a world record by the IAAF, despite being slower than Ted Meredith's mark from 1916. The IAAF rescinded the record on August 7, 1928.
