It was the fifth appearance of the event, which is one of 12 athletics events to have been held at every Summer Olympics. None of the finalists from 1908 returned. The favorites were all among by the American team: 1909 and 1911 AAU champion Edward Lindberg, 1911 IC4A champion Donnell Young, and 1912 IC4A champion Charles Reidpath.[3]
Australasia, Austria, Bohemia, Japan, Portugal, Russia, and South Africa appeared in the event for the first time. The United States made its fifth appearance in the event, the only nation to compete in it at every Olympic Games to that point.
Competition format
The competition consisted of three rounds. The first round had 15 heats, ranging from 1 to 6 runners. The top two runners in each heat advanced to the semifinals. The semifinal was to consist of 5 heats of 6 runners each, but one semifinal had only 5 runners because one preliminary heat had only had 1 runner. Only the top runner in each semifinal heat advanced, making a five-man final. The first two rounds were run without lanes, but an incident in the last semifinal resulted in the final being held with strings demarking lanes.[3][4]
Records
These were the standing world and Olympic records (in seconds) prior to the 1912 Summer Olympics.
(**) This track was 536.45 metres=Шаблон:Frac mile in circumference.
The Olympic record of 48.4 seconds, set at the previous Olympics, fell in the final. Charles Reidpath broke the record with a 48.2 second performance. Reidpath's time was ratified by the IAAF as the inaugural official world record. Hanns Braun also broke the old Olympic record and Edward Lindberg tied it, en route to silver and bronze medals, respectively.
Young crossed the finish line in first, but was disqualified for elbowing Braun and knocking him to the outside of the track as Braun tried to cut in front of him. This incident resulted in lanes being used for the final the next day.[5][3]
The final was held on Saturday, July 13, 1912. It was held in lanes because of the incident between Young and Braun in the semifinals. There were three false starts before the race finally started legally. Meredith led early with a strong pace. Braun took the lead around the halfway mark. Reidpath finished strong, passing Braun in the final 15 metres.[6]
Reidpath's time broke the Olympic record; it was also recognized as the inaugural world record in the event at the formation of World Athletics (then known as the IAAF).
