Usain Bolt retired from professional athletics in 2017. His final major competition was the 2017 World Championships in London, which he had planned as his farewell to individual sprinting.
Bolt finished third in the 100-metre final in 9.95 seconds, behind Christian Coleman and winner Justin Gatlin. It was his first defeat in a major championship 100-metre race, although he had also been beaten in the 2011 World Championships after a false start disqualification.
Bolt attempted one final race in the 4 × 100-metre relay, but injured his hamstring during the final and had to be helped across the finish line by teammates. He did not compete professionally afterward, making 2017 the accepted retirement year.
A common mix-up is 2016, because Bolt initially considered retiring after the Rio Olympics. He returned for one more season before ending his career at the London championships.
