David Lekuta Rudisha is a middle-distance runner. He is the first and only person to ever run 800M under 1:41s and 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 57.69s, and the African record for the 600M, with a time of 1:13.10. Rudisha has won a record three 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.
Initially he was a 400M runner, but his coach, Irishman Colm O’Connell, prompted him to try 800M. In 2006, he became the world junior champion over that distance. In November 2010, at the age of 21, he became the youngest ever athlete to win the IAAF World Athlete of the Year award. He also won the Kenyan Sportsman of the Year award.
At the 2016 Summer Olympics, Rudisha successfully defended his Olympic title, taking gold with a time of 1:42.15. He was the first person since Peter Snell in 1964 to win back-to-back Olympic 800M titles. His finishing time was the fastest he had run since the 2012 Olympic final in London, as well as the fastest time in the world for 2016.
