He is the 2012 and 2016 Olympic champion, 2-time World Champion (2011 and 2015), and world record holder in the 800 metres. Rudisha is the first and only person to ever run under 1:41 for the event, and he holds the three fastest, six of the eight fastest, and half of the twenty fastest times ever run in this event. He also holds the world's best time in the 500m, with a time of 57.69, and the African record for the 600m, with a time of 1:13.10. Rudisha has won a record 3 consecutive Track & Field Athlete of the Year awards (tied with Carl Lewis), and also won the IAAF World Athlete of the Year award in 2010.
Born on 17 December 1988 in Kilgoris, Narok County, Rudisha went to Kimuron Secondary School in Iten, Keiyo District, which is known for nurturing several top runners including Wilson Kipketer, the previous 800 m world record holder, who had already held the record for several years before Rudisha joined the school. In April 2005 Japheth Kimutai recommended Rudisha to James Templeton, and Rudisha joined the group of runners managed by Templeton, which has at various time included Kimutai, Bernard Lagat and Augustine Choge. Initially he was a 400 metres runner, but his coach, Irishman Colm O'Connell, prompted him to try 800 m. In 2006 he became the world junior champion over that distance.
