The world record in the mile run is the best mark set by a male or female runner in the middle-distance track and field event. The IAAF 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, while Svetlana Masterkova has the women's record of 4: 12.56. Since 1976, the mile has been the only non-metric distance recognized by the IAAF for record purposes.
