Stage four cancer patients are determined to live full lives, and few embody that resolve more publicly than Sir Chris Hoy, the six-time Olympic track cycling champion. His mission is to challenge the assumption that a terminal diagnosis means the end of purpose, joy or ambition — and he is doing so through action rather than words alone.
“It’s trying to demonstrate, rather than just talking about it, that all these people who are in a similar situation to me – living with stage four cancer – that there’s plenty of life left in us, and we’re determined to make the most of it, and not have cancer define who you are,” Sir Chris said.
Tour de 4: a ride to redefine what is possible
The demonstration Sir Chris refers to is the Tour de 4, a charity bike ride he is spearheading in Glasgow this September. The event is designed to raise funds for five major UK cancer charities while simultaneously sending a powerful message to anyone grappling with the same diagnosis: that life does not stop at stage four. In its inaugural year, 2025, the Tour de 4 raised more than £3.1 million. The ride is the vehicle through which Sir Chris hopes to shift perceptions — both for those living with cancer and for the wider public who may see only the prognosis rather than the person.
For fellow patients, the message is clear. Sir Chris wants them to know that cancer does not have to define identity or drain the will to live fully. He emphasises that his current health situation is not preventing him from pursuing his passions. The Tour de 4 is both a fundraising platform and a visible, tangible statement that people with stage four cancer can still set ambitious goals, train, ride and inspire others. By cycling through Glasgow alongside supporters and other cancer patients, he intends to show that the disease may be incurable, but the determination to make the most of every day remains undimmed.
Sir Chris’s own journey: from shoulder pain to a stage four diagnosis
Sir Chris’s motivation stems from his own stark experience. He revealed in 2024 that his prostate cancer had spread to his bones, with doctors giving him a prognosis of two to four years to live. The discovery began when he noticed shoulder pain, initially dismissing it as a sign of ageing. Checks later revealed a tumour, which was identified as prostate cancer that had metastasised to his bones, with additional tumours found in his hip, pelvis, spine and ribs. He was diagnosed with stage four prostate cancer.
Since then, Sir Chris has become a prominent advocate for prostate cancer awareness. He encourages men to undergo screening and shares his personal story through public discussions and fundraising events. His documentary, Sir Chris Hoy: Cancer, Courage and Me, detailed his journey and examined how his athletic background has helped him cope. The publicity has generated what experts have dubbed the “Chris Hoy effect” — a notable surge in visits to the NHS website and the Prostate Cancer UK risk checker, which campaigners say may have saved lives.
His advocacy has also shone a light on the UK’s prostate cancer testing and screening protocols. Sir Chris and his wife, Sarra, have met with political figures, including the First Minister of Scotland, to push for changes in how the disease is diagnosed. Current NHS guidelines do not proactively encourage GPs to discuss prostate cancer risk or PSA blood tests with men unless they present with symptoms — a policy that some consider outdated.
Despite the physical toll — including multiple fractures from a mountain bike crash in November that required emergency surgery — Sir Chris has shown remarkable resilience. He returned to cycling and driving within 12 weeks of surgery and underwent intensive rehabilitation. He has spoken frankly about the mental battle, noting that “most of the battle for me with cancer hasn’t been physical. For me, it has been in my head.” He finds positivity by appreciating the present moment and focusing on smaller things in life, rather than dwelling on the future.
Recent updates indicate that his cancer is in a stable phase, managed with ongoing medication and treatment. Sir Chris says cancer is no longer the first or last thing he thinks about each day, suggesting he has successfully integrated his health management into daily life. He believes that advances in treatments, potentially aided by artificial intelligence, offer hope for extending his life — but for now, his focus is on what he can do today: ride, raise money and show others that there is still plenty of life left.
