At the 1952 Olympics in Helsinki, Bannister set a British record in the 1500 metres and finished in fourth place. This achievement strengthened his resolve to become the first athlete to finish the mile run in under four minutes. He accomplished this feat on 6 May 1954 at Iffley Road track in Oxford, with Chris Chataway and Chris Brasher providing the pacing. When the announcer, Norris McWhirter, declared "The time was three...", the cheers of the crowd drowned out Bannister's exact time, which was 3 minutes and 59.4 seconds. He had attained this record with minimal training, while practising as a junior doctor. Bannister's record lasted just 46 days.
