I believe that it is important to learn by example. That's why I decided to post the link below showing Roger Bannister to brake one of the man's greatest barriers; the 4 min mile.
This historic event took place on 6 May 1954 during a meet between British AAA and Oxford University at Iffley Road Track in Oxford. It was watched by about 3,000 spectators.
It is an inspirational video that I hope all will enjoy!
