COCA-Cola Games record holder Batinisavu Uluiyata will be Fiji's sole competitor at the World Junior Athletics Championship.
The Natabua High School athlete will participate in the championship to be held from July 22 to 27 in Eugene, Oregon, USA.
Uluiyata qualified on merit after his record breaking performance in the Oceania Athletics Championships where he clocked 47.67 seconds to surpass the qualifying time of 47.70s.
He first represented Fiji in the World Youth Championships in Ukraine in 2013 and also at the Pacific Mini Games in Wallis and Futuna.
Uluiyata is also a gold medallist in the intermediate grade 200m and 400m in the Coca-Cola Games.
"My aim is to improve my time and I will be running in memory of my mum," said the soft-spoken lad.
Funding for the trip is being made possible through the International Association of Athletics Federations, Fiji Secondary Schools Athletics Association and Athletics Fiji.
Team manager Tevita Nawamea of the Fiji Secondary Schools Athletics Association will accompany Uluiyata on this trip.
The duo are supposed to leave for the US today.
