Fiji's Danielle Alakija has failed to qualify into the next round of the women's 400metres in London.
Alakija raced in heat five and finished with a time of 56.77 - 6 seconds slower than the top qualifier.
But despite her finish, Fiji's track and field coach Roy Ravana says Alakija has a big future.
"She just turned 16 a few weeks ago and got a long way to go and she would be the youngest competing in terms of track and field."
