Wayde van Niekerk produced the best performance of his life on Saturday night, smashing his national 400m record at the Diamond League meeting in Paris.
Van Niekerk seemed to be lagging at the top bend, but he delivered a spectacular effort over the last 200m to chase down half the field, crossing the line in 43.96 seconds to secure victory.
The 22-year-old Free State athlete held off Kirani James of Grenada by 0.21 to beat the world and Olympic champion for the first time in his career.
He improved his own previous national mark of 44.24 set in New York last month, and took 0.05 off Isaac Makwala’s African one-lap record.
Meanwhile, Sunette Viljoen took third place in the women’s javelin throw in the French capital with a 63.15m heave.
Wenda Nel ended fifth in the women’s 400m hurdles event in 54.61.
