Wayde van Niekerk wins Monaco 400m

The world and Olympic champion, also the world record holder in the event, fought off a late surge from Botswanan rival Isaac Makwala to win the 400m at Friday's Diamond League at Monaco. It is no surprise the South African has been hailed by eight-time Olympic champion Usain Bolt as his successor.

South African Wayde van Niekerk fought off a late surge from Botswanan rival Isaac Makwala to win the 400m at Friday's Diamond League at Monaco.

The world and Olympic champion, also the world record holder in the event, hared off down the back stretch in lane five and looked dead set for another straightforward victory. But Makwala, in the lane outside, battled back around the final bend into the home strait. Van Niekerk, however, dug deep and surged home in a meeting record of 43.73sec, Makwala setting a personal best of 43.84 in second.

Van Niekerk is on fire this season, having run personal bests in the 100m (9.94sec) and 200m (19.84) last month, and setting a new world best time of 30.81sec in the rarely-run 300m in Ostrava earlier this month. That time beat a long-time record held by Michael Johnson, the legendary U.S. athlete whose record in the one-lap race he also beat when winning gold in Rio.

In his last Diamond League outing, after Ostrave, the 24-year-old timed a world lead of 43.62sec in Lausanne. Van Niekerk has only run the 400m faster on two occasions: when he won his world title in Beijing in 2015; the other was a year later when he won Olympic gold.

It is no surprise the South African has been hailed by eight-time Olympic champion Usain Bolt as his successor as leader of the sprinting world, with the Jamaican legend due to retire after the world championships in London in August.
