Daniel Wiffen became the first athlete from Northern Ireland to win an Olympic gold medal in 36 years as he triumphed in a thrilling 800m freestyle final in Paris.
The Team Ireland swimmer edged out American Bobby Finke to take gold by 0.56 seconds after a stunning burst of pace over the final 50 metres.
The 23-year-old also set an Olympic record with his blistering finish, recording a time of seven minutes 38.19 seconds.
The pockets of support for Wiffen erupted around the La Defense Arena as he secured a first gold medal of the Games for Ireland.
“I was writing ‘I’m going into the history books’, and that’s exactly what I’ve done,” he told BBC Sport.
“It was definitely the way I wanted to execute it. It wasn’t the time that I wanted, but Olympic finals aren’t about getting times, it’s about getting your hand on the wall first.”
There were tears in Wiffen’s eyes as he received his gold medal at the end of the arena where his family and coaches watched with pride.
After stepping off the podium, he ran over and jumped into the arms of his family – including his twin, Nathan.
He becomes the first athlete from Northern Ireland to triumph since Stephen Martin and Jimmy Kirkwood with GB’s hockey team in 1988 – and the first individual gold medallist since Lady Mary Peters won the pentathlon at the 1972 Games.
He also becomes the first Olympian from Northern Ireland to win Olympic gold for Ireland and the first Olympian from Team Ireland to win a gold medal in swimming since 1996.
Wiffen has now added Olympic gold to his 800m and 1500m triumphs at the World Championships in Doha this year.
