In 1954 Roger Bannister was the first man to break 4 minute mile.
In 1996 Daniel Komen ran 7:20.67 for 3k (worth about 7:54 for a 2 mile), and in 1997 ran 7:58 for 2 miles.
The current 5k world record is 12:37, equivalent to 4:04 per mile pace set in 2004.
So when do we see 12:24, can anyone currently running get there?
