As of my knowledge cutoff in September 2021, the current official world record for running one kilometer without stopping is held by Hicham El Guerrouj of Morocco. El Guerrouj set the world record on July 7, 1999, in Rome, Italy, with a time of 2 minutes 14.96 seconds. This incredible achievement by El Guerrouj showcases his exceptional speed and endurance as a middle-distance runner.


Please note that world records can be broken or updated over time, so it's advisable to consult the latest information from official sports governing bodies or recognized record-keeping organizations such as World Athletics (formerly known as the International Association of Athletics Federations) for the most up-to-date records in running and other athletic events.
