Lady Sarra Hoy has shared her experiences juggling her own health challenges alongside those faced by her husband, Sir Chris Hoy. Cycling legend and six-time Olympic gold medallist Sir Chris disclosed last year that he had been diagnosed with terminal prostate cancer. As if the family wasn't affected badly enough by that revelation, Lady Sarra was soon told she had multiple sclerosis just months later. Speaking on ITV's Lorraine (via The Mirror) in her first solo television interview, Lady Sarra recounted the difficult period after they received their diagnoses. But she emphasised their determination to stay strong for their children: Chloe, seven, and Callum, 10. "You just don't sleep, everything is awful," she told host Lorraine Kelly. "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, I can't control any of that. What can I do? What can I help? What can I change?' "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." Lady Sarra also opened up on how she's managing and exercising control where possible as she added: "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." ITV's March4March initiative aims to support the one in four Brits affected by low mood, highlighting the positive impact of physical activity on mental well-being. Throughout March, Lorraine is encouraging viewers and celebrities alike to commit to walking steps, with the collective goal of reaching three million steps—the equivalent of the length of the United Kingdom. This poignant interview, which airs on Monday morning, follows Sir Chris' surprise announcement regarding his diagnosis last September. The Scot has said it marked the "toughest year of our lives so far by some stretch". "There had been no symptoms, no warnings, nothing," he said before detailing the minimal discomfort he experienced: "All I had was a pain in my shoulder, and a little bit of pain in my ribs." The discovery of his condition came after a scan discovered a tumour, and a subsequent scan two days later revealed the primary cancer in his prostate, which has now spread to his shoulder, pelvis, hip, ribs and spine. With a Stage 4 diagnosis, he was given between two and four years to live. "It was the biggest shock of my life," he said, describing the moments after he learnt of his diagnosis. "I remember the feeling of just absolute horror and shock. "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?'" The family's challenges were compounded when Lady Sarra discovered she had multiple sclerosis three months later, a fact she initially only told her sister. Reflecting on her resilience, Sir Chris said at the time: "The strength of Sarra is unbelievable, she kept it to herself. "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, 'Okay 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 wedded lawyer Sarra in 2010 having received a knighthood in the 2009 New Year Honours for his services to sport following his triple gold triumph at the 2008 Beijing Olympics. He boasts a stunning collection of six Olympic golds and one silver, trailing only Sir Jason Kenny in Team GB's all-time medal count. The champion cycler hung up his competitive helmet in 2013 and has since become a familiar voice as a BBC commentator. Earlier in the year, it emerged Sir Chris is setting up a charity bike event to inspire those with Stage 4 cancer, showing that a full life is still possible. The Tour de 4 cycling challenge is set to both start and finish 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 across Britain have been prompted to get screened for prostate cancer since he went public with his terminal cancer diagnosis last year.
