In a stunning piece of running, South Africa's Wayde Van Niekerk won the 400m Olympic title in a time of 43.03 seconds to smash Michael Johnson's long-standing record. 

The race was billed as a three-horse race between the South African, Kirani James and LaShawn Merritt, but from lane eight Van Niekerk destroyed the field in an incredible time.

As the first man to run a sub-10 100metres, sub-20 200metres and sub-44 400metres, Van Niekerk is already as a star of athletics, but this run will push him to new heights on a memorable night of Olympic track and field.

Hudson-Smith swamped as big three set the pace

Following three fascinating semi-finals on Saturday evening, Merritt and James were drawn alongside eachother in lanes five and six, with Van Niekerk on the outside in lane eight.

Britain's Matthew Hudson-Smith was the unlucky man to be stuck in the middle of the action in lane seven, and the young Midlander was soon overwhelmed by the three favourites who each attacked from the outset.

At the half-way point James and Merritt were neck-and-neck while on the outside Van Niekerk continued to build his lead as the likes of Bralon Taplin and Machel Cedenio in the inside lanes continued to fall back.

Hitting the home straight, Van Niekerk had a healthy lead and instead of struggling over the last 100, he continued to pull away and it became a race between himself and the clock. 

As he surged for the line, the World Record time was revealed, and the crowd went into uproar as a new sporting superstar was born.

Kirani James and LaShawn Merritt continued their scrap for second, and it was Grenada's 2012 champion James who came out on top in a time of 43.76 to take silver, with the American claiming bronze in 43.85.

This race was all about Van Niekerk though, and following on Almaz Ayana's stunning run on Friday in the 10,000, the Rio track has produced some historic times which many hope will continue for the remainder of the meet.
