Former Olympic triathlete Jonny Brownlee has officially retired from professional triathlon at the age of 36. A British athlete with an impressive career, Brownlee won Olympic bronze in London 2012, silver in Rio 2016, and gold in the mixed relay at Tokyo 2020. He also claimed six world titles and mixed team relay gold at the 2014 Commonwealth Games. His younger brother, Alistair Brownlee, a double Olympic champion, retired at the same age in 2024. Jonny told BBC Sport that he had been considering retirement for some time, having achieved more than he ever imagined. He explained that he could no longer commit to the high-performance demands of professional sport, but emphasized that he would not truly stop participating in the sport. The birth of his son, Freddie, 10 months ago, helped solidify his decision to retire. Jonny now prioritizes family and his physical well-being over training. He reflected on how his priorities have shifted, noting that the thought of missing a training session used to be the worst thing in the world. Now, if his son is unwell or needs him, he would put Freddie first. He also mentioned that he no longer feels the same fear of racing, such as diving into corners on his bike at high speeds, as he would now be concerned about being unable to care for his son in the event of an injury. Throughout his career, Jonny cited the London 2012 Olympics and the World Series in his home city of Leeds in 2016 as the moments that resonate most. He expressed pride in earning those medals and noted that the Leeds event symbolized the journey of triathlon. He also acknowledged the unique experience of sharing a long career with his brother, Alistair, calling it "unbelievably special." However, the 2016 World Series Triathlon race in Mexico remained a significant memory. Jonny was leading when his legs gave way on the run leg in extreme heat, and Alistair, who was in third place, helped him finish. While this moment sometimes annoyed him, as it was often remembered more than his other achievements, he remained proud of it, emphasizing the importance of helping others. Jonny mentioned that he knew there was one medal left to claim before stepping away—an Olympic gold. He committed everything to winning mixed triathlon gold at the Tokyo Olympics alongside Jessica Learmonth, Georgia Taylor-Brown, and Alex Yee. He said that if he hadn’t won that Olympic gold medal, there would always be something missing. Winning gold was the moment he was “finally known as Jonny Brownlee, and not as the person who came 10, 15 seconds behind Alistair.” He expressed pride in the impact they had on the sport and said it was time to move on, as he would not be doing himself justice by continuing half-heartedly. Although he is retiring from professional racing, he said he would actually race more in the future.
