Olympic hero Sir Chris Hoy has shared the heart-wrenching reality of dealing with terminal prostate cancer, while his wife Sarra faces an aggressive form of Multiple Sclerosis.

In an emotional account of their struggle, the couple have opened up on their deepest concerns about the future and caring for their children.

Sir Chris's insight emerges ahead of his BBC interview tonight—the first since going public with his diagnosis. His candid reflections are drawn from his forthcoming book, All That Matters: My Toughest Race Yet, as featured in The Times.

He admits, "The future is a great unknown for us both now. There are moments where everything becomes unsteady and life feels too precarious, especially if we think too much about the future and the kids."

He continues expressing his and Sarra's poignant thoughts, adding: "Will we be around to care for our kids, will they be OK? Sarra's treatment can only do so much and her condition is degenerative."

Despite their fears, they strive to maintain hope, with Sarra finding strength in gratitude, "But we find our way back from the pitfall of trying to predict the future. Sarra has found a characteristically courageous way to frame our situation, something we both come back to and feel grounded by."

She offers a touchstone for their resilience, saying, "She reminds me: 'Aren't we lucky? Lucky to both be diagnosed with conditions they have medicines and treatments for. Aren't we lucky that science is ahead of us?'.

"That's what we choose to focus on, rather than asking why we can't be cured," the retired athlete courageously disclosed.

Sports star, Sir Chris, was devastated to learn his life expectancy is now a mere two to four years after what he thought was a simple gym injury led to a prostate cancer diagnosis.

He then discovered the cancer had spread, with tumours found in his shoulder, pelvis, hip, spine, and ribs. On the other hand, Sarra encountered an alarming sensation – a tingling in her face and tongue last summer – which progressed to an MRI referral.

Her latest scans have revealed she suffers from "very active and aggressive MS". Multiple Sclerosis (MS), a devastating neurological disorder that attacks the brain and spinal cord, dismantling the protective covering of nerves, often leads to irreversible damage.

Although treatments are available to manage symptoms, there is unfortunately no cure for MS.

Sir Chris Hoy: Finding Hope airs tonight on BBC One at 8pm.

All That Matters: My Toughest Race Yet is available to buy from November 7.
