Athletics at the 2016 Summer Olympics – Women's 400 metres
[4] In the final, Natasha Hastings made up most of the stagger on one of the favorites, Shaunae Miller and held the lead to the halfway point.Starting about 150 metres into the race, Miller accelerated, passing Hastings before the halfway point in the far turn.In lane 4, Allyson Felix ran an even pace which saw her separate from the athletes inside of her and catching Shericka Jackson late in the second turn.As Felix looked to pass her in the final step, Miller made a last desperate headlong dive across the line.The photo finish revealed her shoulders had crossed the line seven hundredths of a second ahead of Felix.
