After dominating the track events for almost a decade and winning almost all the titles possible, Usain Bolt will be bidding adieu to the sport.
While nobody can truly replace the legendary sprinter, there will be a new 100m champion at the 2020 Olympics.
Let us have a look at some of the youngsters, who could become the next 'Usain Bolt'.
The current world champion in 400m event and world record holder in the 300m race, South Africa's Wayde van Niekerk is a front runner in taking Usain Bolt's place as the world's fastest man.
He also holds a record of being the only sprinter to finish 100m within 10 seconds, 200m under 20 seconds and 400m in under 40 seconds.
Andre De Grasse was Usain Bolt's main rival at the 2016 Rio Olympics in the 100m and 200m events.
The 21-year old Canadian won silver in 100m, and bronze in the 200m race.
While Bolt has himself called De Grasse as his successor, the two won't b able to compete in Bolt's last race after De Grasse withdrew following a hamstring injury.
22-year old Trayvon Bromell earned his name after he recorded a time of 9.84 seconds in the 100m event.
Even though he could not finish in the top three at the 2016 Olympics, he made his mark during 4x100m event.
Bromell is the first junior to finish the 100m race in under 10 seconds.
He was the U-20 champion in the Caribbean tournament, and has also clocked the best time of 10.16 seconds. While he is still young, he has a tough competition from his countrymen Jevaughn Minzie and Kemar Bailey-Cole.
Usain Bolt is also excited to see who would be his successor. He said, "I'm definitely excited just to sit and to see who's going to be the next Olympic champion in the 100 and 200 meters."
He also added, "There are a lot of young stars coming up. It's exciting to see who is really going to step up to be a champion."
