The 24-year-old raced home at the Golden Spike meet at the Mestsky Stadium in the northeastern Czech city of Ostrava in an outstanding 30.81 seconds.
It was the second time the South African has usurped Johnson, having broken his 17-year-old 400m world record when racing to victory at last year’s Rio Olympics.
The wonder-boy’s time also shattered the meet record of 30.97sec, previously the second fastest time every run set by Jamaican sprint star Usain Bolt in 2010.
Despite the fact that this is not officially a record because the 300m marks are not ratified, it nonetheless goes down as a world best.
And we’re proud of our ‘Golden Boy’.
“Thanks to all the people of Ostrava for this wonderful meeting. I’m honoured to be a small part of history.
“I have to rest a little but after that I hope I can continue to make babysteps to be better day by day,” he was quoted.
The Free State MEC for Sport Mathabo Leeto also heaped praises on Wayde.
“The Department is immensely proud of him not only because he is a product of the Free State Sport Science Institute but also because he is an inspiration and role model to many other athletes that the Department aims to develop like we did with him.
We will continue to support and develop Free State athletes to be strong contenders at international platforms hence there is a lot of talent in the province that we continue to unearth.”
