Who was the fastest guy to run a mile?

Answer 1

This is slightly awkward to answer as the mile isn't a "standard" athletic distance nowadays; there's no mile event in the Olympic games for example.

The current record holder is Hicham El Guerrouj who ran a mile in 3:43.13 in Rome in 1999.

Answer 2

The current world record for the fastest mile is held by Hicham El Guerrouj from Morocco, who set a time of 3:43.13 in 1999.
