He and wife Sarra are parents to a son, 10, and daughter, seven

Sir Chris Hoy has revealed the gut-wrenching secret he and his wife are keeping from their two children.

Last year, Olympic gold medallist Sir Chris, 49, was diagnosed with terminal prostate cancer. Shortly after, his wife Lady Sarra was diagnosed with multiple sclerosis.

Now, Chris has opened up about how he and Sarra are approaching family life amid their own health battles.

Chris has been married to Sarra since 2010. The couple are parents to Callum, 10, and Chloe, seven.

In a new interview, Chris opened up about how his cancer diagnosis has affected his children.

Chris also spoke about how his wife’s MS is affecting his family. He noted that Sarra “doesn’t talk about it a massive amount” but said she “gets good days and bad days”.

If it wasn’t for my diagnosis, I think it would be getting a lot more attention, but she likes it that way. She doesn’t want the focus, she just wants to crack on.”

In January, Chris told the BBC that the first few months after receiving his diagnosis were “an emotional rollercoaster”. It was particularly heartbreaking to have to tell his kids, he said.

However, he said he’s more or less got his head around it now. And raising awareness of prostate cancer has lifted him and given him a purpose
