Miller denies
Felix fifth gold in photo finish
Allyson Felix missed out on becoming the first female athlete to win five
Olympic gold medals in track and field, with Shaunae Miller diving over the finish line to edge out the reigning champion in the
400m with a time of 49
.44.
Felix had been favourite to add to the golds won in
Beijing and
London, but she left herself too much to do on the
home straight - and Miller of the
Bahamas threw herself to victory. The bronze went to
Jamaica's Shericka
Jackson in a time of 49.85.
