Usain Bolt cemented his position as the fastest person in human history with another outstanding performance at the Olympics. For the third straight time at the Summer Games, the Jamaican sprinter completed a clean sweep in his three events, totaling nine gold medals in his career.

After finishing in first place in the men’s 100-meter, 200-meter and 4x100-meter relay in Rio, what’s next for Bolt? Having dominated the Olympics since 2008, the greatest of all time says he won’t compete at the 2020 Summer Games in Tokyo.

“What else can I do to prove to the world I am the greatest?” Bolt said after he won his final individual gold medal.

“I don’t need to prove anything else. I came to prove to the world I’m the best and uplift the sport."

But just because Bolt won’t be competing for more Olympic gold, that doesn’t mean his time in the spotlight is finished. He’ll run at the 2017 World Championships in London, where he’ll end his illustrious career.

Before last year’s World Championships in Beijing, Bolt said he had originally planned to retire after the 2016 Olympics. Instead, he’ll compete at the upcoming World Championships, where he has 11 first-place finishes.

“I'll be doing one event, the 100,” Bolt told the Daily Mail last year. “I've already discussed it with my coach. I can concentrate on that, and on retiring on a winning note."

Bolt has been nearly perfect at the World Championships, which are held every other year. Since 2009, he’s failed to finish in first in his three races just once. He was disqualified from the 100m race in 2011 because of a false start.

Both of Bolt’s world records were set at the World Championships, not the Olympics. His 9.58-second sprint in the 100m and his 19.19-second finish in the 200m both came at the 2009 World Championships in Berlin.

The 2017 World Championships are scheduled for almost exactly a year after the Rio Olympics. The men’s 100m preliminary is set for Aug. 4, 2017, and the final will be held the following day.
