05:10 The mile has a long history, starting with the ancient Greeks who measured it as a stade, and later the Romans who marked their distance every thousand strides, and eventually the Brits who established the mile as eight furlongs, but today the mile is not a regular race in the Olympics.

10:52 In the 19th century, the mile race became increasingly popular, with Captain Robert Barclay being the first person to break the five minute mark, and by the end of the century, runners were getting closer to breaking the four minute mile.

15:55 In 1886, Walter George ran a mile in four minutes and 12 seconds, which was close to breaking the four minute mile and inspired elite runners around the world to chase that record.

21:09 In 1945, two Swedish runners, Gunder Haag and Arnie Anderson, became the world's best runners and had a famous race in Malmo, Sweden, where Haag won and set a new record of 4:01.4, coming close but not quite reaching the four minute mile mark.

26:13 Some people believed that the four minute mile was within reach, while others, like track coach Brutus Hamilton, believed it was impossible due to the physiological limits of the human body, but every single one of Hamilton's limits had been broken at least once, and Roger Bannister, a British runner and Olympic caliber athlete, was determined to prove that the four minute mile was possible.

31:20 Roger Bannister decided to set his sights on the 1952 Olympics in Helsinki and train for those instead of rushing to enter the 1948 Olympics, showing his mental discipline and lack of faith in his abilities to win gold.

36:24 After a disappointing performance at the 1952 Olympics, Roger Bannister decides to shift his focus to breaking the four-minute mile and conducts scientific studies on the physiological effects of running to gain an advantage over his competitors.

41:26 Roger Bannister's strategy for breaking the four-minute mile included conserving energy, improving his cardiopulmonary limits, and using pacers to help him maintain his pace.

46:46 Roger Bannister broke the four-minute mile record in a time of three minutes, 59 and four tenths seconds, becoming the first person in history to achieve this feat, and although his record was broken within six weeks, it remains a significant accomplishment.

52:03 Roger Bannister breaking the four-minute mile barrier inspired others to believe it was possible, and he went on to live a long life filled with accolades and recognition for his achievement.
