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.
