They thought it couldn't be done, but he's done it.
And he's barely 19 years old.
National sprinter Khairul Hafiz Jantan shocked the nation when he clocked a personal best of 20.90 seconds in the 200m event - breaking a 49-year-old national record in the process.
The lad, who will be turning 19 this Saturday (22 July), broke the record held by Malaysian legend Tan Sri Dr M. Jegathesan at the Malaysian Open Athletics Championships on Tuesday, according to a report by The Star Online.
Jegathesan set the record with a time of 20.92 seconds in the semi-finals of the 1968 Mexico Olympics.
Sarawak's Jonathan Nyepa finished second with a time of 21.29 seconds and G. Aravinn Thevarr of Perak clinched the third place in 21.31 seconds.
With that achievement, the sprinter from Melaka became only the third Malaysian to beat the 21 second mark, behind Jegathesan and Azmi Ibrahim (he clocked 20.98 seconds at the 2001 SEA Games).
After the event, Khairul told the news portal that he didn't expect to break the long-standing record, as he only managed 21.08 seconds in the qualifying rounds.
"I had a very good start and I ran as fast as I could. I jumped for joy when I saw on the electronic board that I had clocked 20.90,” he was quoted as saying.
This is not the first time the teenager broke a long-standing national record, though.
Back in July 2016, he broke Watson Nyambek's 18-year-old 100m national record when he crossed the finish line in 10.18 seconds at the Sukma Games.
The future is really bright for young Khairul and hey, who knows one day he'll be able to break the world record, right?
Just keep running, Khairul!
