Wayde van Niekerk: South African creates sprinting history

Wayde van Niekerk won the 400m title at the 2015 World Championships in Beijing

South Africa's Wayde van Niekerk has become the first athlete to run under 10 seconds for the 100m, 20 seconds for the 200m and 44 seconds for 400m.

Van Niekerk ran 100m in 9.98 seconds in Bloemfontein on Saturday to add to his 19.94 personal best over 200m and 400m world title-winning 43.48.

The 23-year-old was helped by a legal 1.5m/sec tailwind and 1,300m altitude.

"Wow! Finally reaching my dream of sub 10," Van Niekerk wrote on Instagram alongside a video of the race.

Former world and Olympic 200m and 400m champion Michael Johnson wrote on Twitter: "Sub 10, sub 20, sub 44. That's crazy. Great things could be ahead."

Van Niekerk will only run the 400m at the Olympics in Rio this summer.
