Sir Chris Hoy gives an update about living with stage four cancer: 'I'm doing pretty well really'

"I'm doing pretty well really, I was diagnosed with stage four so it's incurable, it's spread to my bones and I will live with it for the rest of my life," Hoy said.

Hoy said the diagnosis still stands out to him because he did not see it coming. "It was a huge shock, I thought prostate cancer was something for men over 50."

He knew the disease ran in his family, but there were no warning signs. "My grandpa had it, my dad had it so I was aware of it and yet I assumed you'd see some sort of change, that you'd notice it, but there was nothing. The first thing I noticed was my shoulder and that was a sign it had spread from my prostate."

Hoy was diagnosed in September 2023, when he was 47. In an interview with The Sunday Times in October 2024, he revealed that the cancer was terminal and that doctors had given him two to four years to live. Since then, he has published a memoir and campaigned for better prostate cancer screening for men.

Hoy then gave men some practical advice on checking their own risk:

Going public has already had a measurable effect. Prostate Cancer UK chief executive Laura Kerby said that over 286,000 people used the charity's online risk checker in the few months after Hoy shared his diagnosis. Hoy also set up his own charity ride, Tour de 4, which aims to change how people see stage four cancer.

Evans' 4 Nations Cycle Challenge is the longest fundraising challenge Radio 2 has ever taken on. Day one covered 84 miles (135km) from Glasgow to Cairnryan in south-west Scotland. From there, Evans takes the ferry to Northern Ireland, and the ride finishes in central Cardiff on Friday 13 November.

Hoy warned that the opening day would depend heavily on the wind, and said Evans would need to remind himself why he was making the journey.

A film about the ride will air on BBC One on Friday 20 November at 7.30pm.
