Mile run world record progression
The world record in the mile run is the fastest time set by a runner in the middle-distance track and field event. World Athletics is the official body which oversees the records. Hicham El Guerrouj is the current men's record holder with his time of 3:43.13,[1] while Faith Kipyegon has the women's record of 4:07.64.[2] Since 1976, the mile has been the only non-metric distance recognized by the IAAF for record purposes. However, in international competitions such as the Olympics the term "mile" almost always refers to a distance of 1,500 meters, which is 109.344 meters shorter than an Imperial mile, even though four "full" laps of a 400 meter track is equal to 1,600 meters.
Accurate times for the mile run (1.609344 km) have been recorded since 1850, when the first precisely measured running tracks were built. Foot racing had become popular in England by the 17th century, when footmen would race and their masters would wager on the result.[citation needed] By the 19th century "pedestrianism", as it was called, had become extremely popular and the best times recorded in the period were by professionals.[citation needed] Even after professional foot racing died out, it was not until 1915 that the professional record of 4:123⁄4 (set by Walter George in 1886) was surpassed by an amateur.[citation needed]
Progression of the mile record accelerated in the 1930s as newsreel coverage greatly popularized the sport, making stars out of milers such as Jules Ladoumègue, Jack Lovelock, and Glenn Cunningham. In the 1940s, Swedes Arne Andersson and Gunder Hägg lowered the record to 4:01.4 while racing was curtailed during World War II in the combatant countries. After the war, Roger Bannister of the United Kingdom and John Landy of Australia vied to be the first to break the fabled four-minute mile barrier. Roger Bannister did it first on May 6, 1954, and John Landy followed 46 days later.
On the women's side, the first sub-5:00 mile was achieved by the UK's Diane Leather 23 days after Bannister's first sub-4:00 mile. However, the International Association of Athletics Federations (IAAF) did not recognize women's records for the distance until 1967, when Anne Smith of the UK ran 4:37.0.[3]

As there was no recognized official sanctioning body until 1912, there are several versions of the mile progression before that year. One version starts with Richard Webster (GBR) who ran 4:36.5 in 1865, surpassed by Chinnery in 1868.[4]
Another variation of the amateur record progression pre-1862 is as follows:[5]

IAAF / World Athletics era
[edit]The first world record in the mile for men (athletics) was recognized by the International Amateur Athletics Federation (later known as the International Association of Athletics Federations and currently known as World Athletics) in 1913.
To June 21, 2009, the IAAF has ratified 32 world records in the event.[6]

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 for the mile were rounded up to the nearest tenth of a second commencing January 1, 1957. Previously, records were rounded up to the nearest fifth of a second. Those rounded-up marks were: Cunningham's 4:06.8 (timed at 4:06.7); Hägg's 4:06.2 (4:06.1); Hägg's 4:01.4 (4:01.3); Landy's 3:58.0 (3:57.9). Landy's mark was not retroactively adjusted when the new rule came into effect.[33]: vii, 69–70 Auto times to the hundredth of a second were accepted by the IAAF for events up to and including 10,000 m beginning in 1981.[6]
During the most recent world record setting race in 1999, Noah Ngeny came in second place to Hicham El Guerrouj with a time of 3:43.40, which continues to be the second fastest mile run in history, beating out the old world record set in 1993 by Noureddine Morceli.[34] No-one else approached the record in the 21st century until September 16, 2023, when Jakob Ingebrigtsen and Yared Nuguse recorded the third and fourth fastest times in history, with 3:43.73 and 3:43.97 respectively.

Note:
- Decker ran 4:17.55 indoors in Houston on 16 February 1980, but this time was rejected as a record due to an oversized track.
- Natalya Artyomova (Soviet Union) ran 4:15.8 in Leningrad on 6 August 1984, but this time was rejected as a record due to there being no international judges.
