Bahamian Shaunae Miller launched herself over the finishing line with a desperate dive to pip American Allyson Felix to Olympic 400 metres gold by the slimmest of margins in a thrilling final
After literally flying across the line in a personal best time of 49.44 seconds, the 22-year-old lay on the track, shaken up and exhausted, as she waited for the scoreboard to confirm she had clinched her first major title.

USA's Allyson Felix took silver with 49.51sec while Shericka Jackson of Jamaica claimed bronze in 49.85

IS DIVING ALLOWED? 

Diving is a subject of much controversy, but the rules have always been clear: 'The first athlete whose torso (as distinguished from the head, neck, arms, legs, hands or feet) reaches the vertical plane of the closest edge of the finish line is the winner.' 

Brazilian hurdler João Vitor de Oliveira dove across the finish line and earned himself a spot in the 110m semifinals just earlier Monday evening Aug 15,2016

In the 2008 Olympics, American sprinter David Neville earned bronze after diving in the the 400m final.
