Jonathan Fox says breaking the world 100m backstroke record has spurred him on to achieve even more in future.
Fox, who was born with cerebral palsy, won gold at the International Paralympic Committee World Swimming Championships in Eindhoven.
The 19-year-old told BBC Cornwall: "It was an awesome race against all of my rivals, so it was a really good race.
"It's like a stepping stone for me really and just makes me want to progress in future competitions."
Fox's world record time of one minute, 11.94 seconds was five hundredths of a second faster than his previous best of 1:11.99, set in April in Sheffield.
"I wanted that world record so much and I just went into the race hungry for it," he added.
"I went into this meet wanting success and I am happy with how my racing has gone."
Fox also won gold in the 100m backstroke (S7 category) at the Paralympic World Cup in Manchester in June.
