set on July 12, 2019. Men Pre-IAAF Professionals Amateurs 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. Another variation of the amateur record progression pre-1862 is as follows: IAAF era 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. 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. 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. 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. Men's Indoor Men Indoor Pre-IAAF Men Indoor IAAF era The IAAF started to recognize indoor world records in 1987, with the then world's best time, Coghlan's 3:49.78, ratified as the inaugural record for the mile.
