SIR Chris Hoy's wife has opened up about the Olympic legend's battle with terminal cancer and her own health struggles. Cycling and Team GB icon Hoy, 48, revealed that he's battling terminal prostate cancer in a brave Instagram post last year. Shortly after, his wife Lady Sarra Hoy was diagnosed with Multiple Sclerosis - a condition that affects the brain and nerves. In an intimate conversation with ITV's Lorraine, she spoke of the challenges the couple had faced over the past two years. Lady Sarra said: "You just don't sleep, everything is awful. "It was about trying to control what I could, and I just thought, I can't do anything about cancer, I can't do anything about MS [Multiple Sclerosis], I can't control any of that. "What can I do? What can I help? What can I change?" She told how they both had to dig deep amid the mental anguish as they both refused to be bowed by their circumstances. Lady Sarra added: "When everything is spiralling just to stop and say, 'right now, we're safe, the children are safe, this can't define us. We will not become the victims of this. "With kids you don't get a chance, there's no time to stop and have a day in bed, you just don't get that opportunity. "So yes, the children are everything for us and our family that surrounds us are everything." Opening up about how she is coping, Sarra said: "It's been okay and I think people are really surprised to know that you can sort of be okay, and I think that's definitely what's helped us get through." The candid conversation took place on ITV's 'Lorraine' as part of the show's March4March campaign. The campaign aims to encourage movement and exercise to improve mental health Six-time gold medallist Hoy was diagnosed with cancer two years ago before revealing the news to the public in 2024. The Olympic legend was told he had cancer in late 2023 after he sought treatment for a strain in his shoulder. After undergoing scans, it was found the cycling great had a tumour in his shoulder and cancer in his prostate. The prostate cancer then metastasised to his bones as doctors soon found tumours in his shoulder, pelvis, spine and ribs. He brought Murrayfield to a standstill as the crowd rose to its feet for a standing ovation last month. Since going public, Hoy has spearheaded several initiatives to raise awareness and funds for cancer research. His Tour de 4 Ride campaign aims to help to change the perception of people living with stage four cancer. Sir Chris also presented the the Ballon d’Art trophy to Luke Littler a few days before the teen was crowed world champ in January. Getting his message across Back in December, just a few months after his terminal cancer diagnosis reveal, Hoy appeared at the Sports Personality of the Year Awards. The appearance came a week after he poured his heart out on ITV's Lorraine - revealing how he and wife Sarra broke the news of his illness to their two children. He took to the SPOTY stage soon after to give an impassioned speech about Team GB's efforts at the Paris Olympics. As he addressed his audience, he relayed what it takes to be represent your country at the Games. Rather brilliantly, Hoy has also been able to appeal to men at major sporting events. Back in January, he was invited by Paddy Power to the World Darts Championship final. The bookies pledged to donate £1,000 for every 180 thrown, as well as a bonus £120,000 for every nine-darter thrown to Prostate Cancer UK. In the end, they managed to raise a staggering £1million for the charity.
