Sir Chris Hoy's wife reveals why she kept health battle secret after his terminal cancer diagnosis

Team GB Olympic legend Sir Chris Hoy has opened up on his battle with terminal cancer, in an emotional live interview with wife Sarra.

Hoy, who's been told he has four years to live, was first diagnosed with cancer in September last year, and was appearing on Tuesday's version of This Morning to chat about his current condition, as well as his new book, All That Matters.

The six-time Olympic cycling champion was joined by wife Sarra, and recalled the moment he felt his first initial symptom.

He explained he felt "something was wrong" after noticing a pain in his shoulder, which made picking things up more difficult. However, he admits he "never considered it might be cancer."

"I had this pain in my shoulder and it wouldn’t go away," he said. "I was 47 then, still lifting weights in the gym, still physically active. You’re used to having aches and pains [at that age] but this one didn’t go away.

“I went to get the scan at the doctor's surgery and they brought the scan up and said ‘there’s a tumour on your shoulder, we need to find out what the root of this is’ so I had multiple other scans and eventually the root of it was a prostate, and it was stage 4 prostate cancer, which had spread to the bones.

"[I had] no symptoms, nothing to point to this diagnosis until the shoulder pain, so it came out of the blue. I always prided myself as someone who would go to the doctor with illness or pain.

"As part of being an athlete, you’re used to looking after your body and being quite aware of yourself, but in this case, it was too late by the time we had actually found the diagnosis.”

Recalling the moment doctors broke the news to him, Hoy added: “We were in the room, and we got the diagnosis and I felt sick, I felt nauseous and the room felt like it was spinning.

"I had to get up but I couldn’t sit still and it’s not the news that you can ever prepare yourself for.

"You can never imagine yourself in that situation and a million thoughts are running through your head. The first one was ‘how on earth are we going to tell the kids?’”

Wife Sarra, with whom Hoy has two young children, recently shared that she's also battling multiple sclerosis (MS), and hid her diagnosis from her husband as his cancer news came out.

Explaining her decision to keep her diagnosis from her husband, she said: “It came completely out of the blue and I just knew it wasn’t the right time.

"I always tell Chris everything and we are always each other’s crutch in everything in life so it was very against the grain to not share it with him but I just knew it wasn’t the right time. We were trying to find stable ground having just been given this diagnosis from him.”
