Shaunae Miller wins women's 400m thriller

Shaunae Miller claimed a thrilling win in the women's 400 metre final at the Rio Olympics, holding off Allyson Felix.

The Bahamian sprinter held on for the most remarkable of wins, falling over the line to take gold in 49.44 seconds on Monday.

Felix, a four-time Olympic champion, was coming from behind and looked set to catch Miller.

But Miller managed to hold on, take victory following a photo finish ahead of Felix (49.51secs) and Jamaica's Shericka Jackson (49.85secs).

She looked certain to be caught after making a blistering start from lane seven, but the world championship silver medallist just held on.

The 22-year-old's triumphed marked the first medal claimed by the Bahamas at the Rio Games.
