Lady Sarra Hoy, wife of Sir Chris Hoy, has given a heartfelt account of their personal struggles in her first solo television interview. Last year, the 48 year old cycling legend and six-time Olympic gold medallist, Sir Chris, shared his diagnosis of terminal prostate cancer. Not long after, Lady Sarra herself was diagnosed with multiple sclerosis. In an intimate conversation with ITV's Lorraine , Lady Sarra Hoy spoke of the challenging period following their diagnoses and the resilience they've shown for their children Chloe, aged seven, and Callum, aged 10. "You just don't sleep, everything is awful," Lady Sarra said of learning the news. "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 and how she is trying to control what she can, 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 initiative is particularly focused on supporting the one in four Brits who struggle with low mood, highlighting the positive impact of physical activity on mental well-being. Throughout March, viewers and celebrities will be encouraged to commit to a collective goal of 3 million steps—the equivalent of walking the length of the UK. The new interview - which is airing on Monday morning on the hit daytime programme - comes after Sir Chris shocked the sporting world with news of his diagnosis. He described the diagnosis - in September 2023 - as "completely out the blue", adding that it had been the "toughest year of our lives so far by some stretch." He said that there had been "no symptoms, no warnings, nothing," adding: "All I had was a pain in my shoulder and a little bit of pain in my ribs." A scan revealed a tumour, while a second scan two days later found the main cancer to be in his prostate which has since metastasised to his shoulder, pelvis, hip, ribs and spine and was stage 4. He has two to four years left, he said. "It was the biggest shock of my life. I remember the feeling of just absolute horror and shock," he revealed last year. "I just basically walked back in a daze. I couldn't believe the news and I was just trying to process it, I don't remember walking. I just remember sort of halfway home thinking 'where am I?' And then I was thinking 'how am I going to tell Sarra? What am I going to say?'." But things got worse, as wife Sarra learned three months later she had multiple sclerosis, only sharing the news with her sister. "The strength of Sarra is unbelievable, she kept it to herself," Sir Chris explained at the time. "Throughout all of that she was there for me but didn't at any point crack. And it was really only in December that she said 'this is the news I've had'. "That was the lowest point I think. That was the point where I suddenly thought 'what is going on?' I almost felt like saying OK stop, this is a dream, wake me up, this isn't real, this is a nightmare. You were already on the canvas and I just felt this, another punch when you're already down - it was like getting that kick on the floor." Sir Chris married lawyer Sarra in 2010. He was knighted in the 2009 New Year Honours list for his services to sport, after winning three gold medals at the Beijing Olympics in 2008. He has won six Olympic golds and one silver overall - the second highest tally by a British Olympian behind Sir Jason Kenny's seven Olympic titles. He retired in 2013 and is now a BBC commentator. Earlier this year it was revealed that Sir Chris is organising a charity cycle ride to show people with Stage 4 cancer can still live life to the full. His Tour de 4 bike ride will start and end at the Sir Chris Hoy velodrome in Glasgow on September 7. He said: "It's important to demonstrate it is possible to live well and lead a happy life alongside this devastating diagnosis." More than 300,000 men in Britain have had checks for prostate cancer since Sir Chris announced last year he was terminally ill with the disease.
