Six-time Olympic cycling champion Sir Chris Hoy says he is “optimistic, positive and surrounded by love” after revealing he was diagnosed with cancer last year.

The former Great Britain track cyclist, 47, posted on Instagram that his treatment, which includes chemotherapy, “is going really well”.

“I am continuing to work, ride my bike and live my life as normal,” he added.

Hoy won six Olympic golds between 2004 and 2012.

The Scot, also an 11-time world champion and the second most decorated Olympic cyclist of all time, said that his diagnosis came as a “huge shock, having had no symptoms”.

He added: “For the sake of my young family, I had hoped to keep this information private but regrettably our hand has been forced. Whilst I’m thankful for any support, I’d like to deal with this privately.

“I’m optimistic, positive and surrounded by love for which I’m truly grateful. As you might imagine, the last few months have been incredibly difficult. However, I currently feel fine.

“It’s an exciting year of work ahead, not least with the Paris Olympics in July. I can’t wait to get stuck in, have fun and share it with you all.”
