Millfield School pupil James Guy picked up his third medal of the week at the FINA World Junior Swimming Championships in Dubai as he struck gold with the British 4x200m freestyle relay team.
Guy, who had already won silver medals in both the 200m and 400m individual freestyle, produced a storming last leg to bring the quartet home in a Championship record time of 7mins 15.36secs.
"We’re all really pleased with that," said the 17-year-old, who also excelled in the senior World Championships in Barcelona last month.
"To drop four seconds [from the morning qualification time] and get a new Championship record is a fantastic result."
After a solid start from Matthew Johnson, Max Litchfield took over to keep the British quartet in the race before Caleb Hughes got them back in front, setting Guy up to grab the glory.
"I’m astounded," said Hughes. "We had a good lead off from Jonno, he put us in good standing. Max is always the speed king bringing it back and we knew we had Jimmy on the last leg to give it the big one and he did it well.
"I want to thank these boys, we did our best and got gold."
Bath ITC's Graeme Antwhistle, British head coach for the meet, said: "We have spoken about maintaining momentum through the meet after a good start on Monday.
"The swimmers have remained professional and as a team have really responded to the challenge.
"The results tonight have been outstanding and have demonstrated the drive within this team to perform to the potential that we know they have.
"The swimmers believed they could achieve tonight when they walked out into the finals, and that is a great quality to have."
