You get the first thing ticked off the list and you’re on the way. It was the catalyst which started my swimming career,” Wiffen told BBC Sport NI.”The Commonwealth Games silver sits over my head as I wish I won it, but I’ve always said in 2026 I want to win every competition. “I had a bit of a drought before the Europeans and I wasn’t in my top form for like a year and I think Commonwealth Games, I’m looking forward to getting my redemption and getting a gold medal – at least one – and to be honest, I want three but I have to see.”Dealing with newfound fame after ParisWiffen won Olympic gold in the 800m and bronze in the 1500m in Paris two years ago [Getty Images]Life has changed drastically for Wiffen since Birmingham four years ago as a result of his success in the pool.He is now regularly stopped in the street for photographs and has enjoyed his newfound fame.”I like it, it’s cool people recognise the hard work you put in. I’ve been swimming since I was seven and my parents always said they never thought I’d become a celebrity in Ireland. You get a lot of free stuff which they like!” he joked.Wiffen also gives an insight into life as a high-performing athlete by regularly posting YouTube videos on a channel he shares with his twin brother Nathan. The channel has gained over 100,000 subscribers and the 24-year-old believes the experience of posting videos in which he talks to a camera has helped him with media duties as a swimmer.”For Paris I was posting videos all the way along and people were like you should stop and hide it but I was like, to be honest, I’m training faster than anyone else and I’m making them scared,” he said.”People find media interviews daunting but I think because I started my YouTube channel when I was 18 and I’ve been doing that, I’ve become quite good on camera and quite good at being myself instead of putting on a fake persona that other people do.”‘Nothing is going to stop me’Wiffen is part of Team NI’s 15-strong swimming squad heading to Glasgow and is one of their genuine multiple medal contenders, although he would rather refer to himself as a “medal guara
