I once ran a mile in under 4 minutes, can you bet that? The history of the mile run event began in England, 
The best I can do is in grade school I ran a 7 minute mile. How did you train to get so fast?
I practice every morning, that was how I trained myself,  In spite of the roughly equivalent 1500 metres race, the mile run is present in all fields of athletics
Do you know when it started to be ran as an athletic event?
Oh yes, the history of the mile run began in England and it initially found usage within the wagered running contests of the 18th and 19th century.
