At just 12 years old, China’s Yu Zidi is already one of the fastest swimmers in the world.

Her times are so quick in fact, that she’s already in contention to win medals at the World Aquatics Championships in Singapore in the coming days.

World Aquatics has a minimum age requirement of 14 for the world championships, but Yu’s times are so fast that she qualifies regardless.

The youngster, not yet a teenager, will race in the 200m and 400m meter individual medleys, as well as the 200m butterfly. The precocious pre-teen may also be selected for China’s relay teams.

It will mark the first time in her incredibly short career that Yu will come up against the very best in the world – many of whom will have paid attention to the staggering times she has set in her country so far.
