Sir Chris Hoy and his wife Sarra spoke to Sally Nugent and Jon Kay live on BBC Breakfast09:38, 02 Sep 2026Sir Chris Hoy spoke candidly about his cancer diagnosis live on BBC Breakfast.‌The six-time Olympic cycling champion was diagnosed with stage 4 prostate cancer in September 2023. He announced the news a year later, revealing that his cancer had spread to his bones.‌He previously told the Sunday Times: "As unnatural as it feels, this is nature. You know, we were all born and we all die, and this is just part of the process. You remind yourself, aren't I lucky that there is medicine I can take that will fend this off for as long as possible."‌Since his diagnosis, Chris has called for a national screening programme and urged more men to get tested for prostate cancer. This weekend, Chris will host his annual charity cycling challenge, Tour de 4, which aims to change public perceptions of living with a late-stage diagnosis, and raise vital funds for cancer support services across the UK.The event will take place on Sunday (September 6). It will start and finish at the Sir Chris Hoy Velodrome in Glasgow, featuring four distinct routes that are tailored to different fitness and ability levels.‌Chris appeared live on the BBC Breakfast sofa on Wednesday (September 2), alongside his wife Lady Sarra Hoy, to look ahead to the event. He also shared a health update with hosts Sally Nugent and Jon Kay."How are you?" Sally asked, with Chris replying: "We're busy, all going well. It's a busy week leading up to the Tour de 4."Healthwise, [I'm] good. Pushing on. But yeah, it's just a really exciting time. Watching that little montage there, brings back the memories and we're both really excited."‌Sarra added: "Yeah, really excited, and keeping well. And who would have thought a year on and here we are, still raring to go. There's just so much encouragement and energy from everybody that is really helping feed us."Sally then noted: "I want to talk a little bit about Tour de 4. Stage 4. That number is really important, isn't it? Because stage 4, a diagnosis of stage 4 cancer, it's the worst one that you can get. There's no stage five. And I wonder if what you're doing at the moment is changing the way that people think about that number and what that means about the life that you can live."‌Chris replied: "In that moment, when you're given that news, all hope is stripped away. And as you say, there's no stage five, six, seven, eight. So, it's like, 'Well, this is the end of the line.'"And for many people, sadly they don't have that much time. But [if you do] a bit of homework, you realise that some people can live for many, many, many years with stage 4 cancer."So, aside from the money, [the] fundraising element to it, the aim with Tour de 4 is to show that while life goes on, make the most of it... And there's so many people within the bunch who are exactly the same as me, who are living with stage 4 cancer."Article continues belowChris then revealed that spectators will be able to distinguish those who are living with stage 4 cancer at this weekend's Tour de 4, as they will each be wearing a "special" armband.BBC Breakfast airs daily on BBC One at 6amIf you would like more information or support about living with prostate cancer, visit Prostate Cancer UK
