The age limit for competing in the Olympic Games varies with each international sports federation, according to the official website of the Olympic Movement. The Olympic charter does not set an age limit for competitors in the Olympic Games.
International sports federations are responsible for setting the age limits and laying down other rules to govern the sports. In the 2012 London Olympics, the average age of Olympians was 26. A total of 33 Olympians aged 15 and under competed in the games, with the youngest being 13 years old. On the other hand, the oldest competitor was 71 years old.
