Steven Gardiner dedicated his 400 metres world title to the people of the Bahamas after the devastation wrought by Hurricane Dorian last month.
The 24-year-old, a silver medallist in 2017, timed a national record of 43.48 seconds and said thoughts of the damage and loss of life Dorian incurred were in his mind before the race.
For Gardiner, whose compatriot Shaunae Miller-Uibo donated $25,000 before the championships and set up an account for donations to the disaster fund, it was personal too as he has a house on Abaco, one of the islands most badly affected.
The island communities of Grand Bahama and Abaco bore the brunt of Dorian's fury in early September leaving 52 people dead with over 1,000 still listed as missing a few weeks ago.
"It will mean a whole lot to the people of the Bahamas that I won and Shaunae got silver last night (400m) in what has been a rough time for the islands," said Gardiner.
"It was going through my head before the race but not during it as I was focussed only on winning the title and bringing some joy to the people."
"I wanted to give them a bit more than my best. I wanted to be a world champion and here I am now."
"Everybody got evacuated. My house was damaged but not destroyed." -
