Sir Chris received his diagnosis in September 2023 and made it public a year later.

The Scotsman has been undergoing chemotherapy after doctors gave him a prognosis of two to four years.

Speaking to Sky Sports, Sir Chris said: “I’ve smashed my leg up on the mountain bike, that’s the worst thing that’s happened recently.”

The accident occurred while the 49-year-old was riding his mountain bike, resulting in a hard landing when he came off the saddle.

He is currently moving about on crutches as he recovers from the injury.

Despite the setback, the Olympic champion remains upbeat about his mobility improving in the coming weeks.

The father-of-two remains confident of appearing at the World Darts Championship in January.

He told Sky Sports: “It was a big one. I’m doing better now, I’m still on crutches, hobbling about, but by the time I’m there for the darts final on January 3, hopefully I’ll be a bit more mobile.”

Sir Chris presented Luke Littler with his trophy at last year’s final.

He reflected on the incident with characteristic perspective, noting that bodies simply do not recover as easily with age.

“You just don’t bounce like you do when you’re younger,” Sir Chris said.

The Scot emphasised he does not consider himself someone who takes excessive risks, but remains determined to embrace life fully.

“None of us are here forever, so you want to make the most of the time you have and do the things you enjoy,” he added.

Describing the crash as simply “the way the cookie crumbles,” Sir Chris added that while he struggled initially after the accident, he is now looking forward to the festive season.

Reflecting on his cancer journey, the 49-year-old explained that the initial period following his diagnosis more than two years ago was particularly difficult.

However, Sir Chris has responded well to treatment and entered a phase of relative stability.

He acknowledged that the disease can return, requiring changes to his treatment plan, but expressed gratitude for the multiple options available to prostate cancer patients.

“It’s putting faith in science and knowing that right now, today, there are countless people all around the world working on new medications, new treatments, and with the hope that one day it won’t be a terminal diagnosis, but I’m doing fine,” he said.

Sir Chris has also spoken candidly about his wife’s battle with multiple sclerosis.

Sarra, who tied the knot with the cyclist in 2010, was diagnosed with the autoimmune disease shortly after Sir Chris received his own diagnosis.

Speaking last week, Sir Chris said: “She’s doing fine. It was the final kick in the teeth when you thought it couldn’t get any worse.

“To get that news literally a month or two after my diagnosis, that was the lowest point really.

“But she’s an incredible human being. We’re still pushing on and we’re still having fun. We’ve got the house decorated for Christmas. There are times when it’s tough but we’re doing really well.

“There are times where you forget about it. It’s not like two years ago when you woke up and the first thing you thought about was cancer.”
