Six-time Olympic champion Chris Hoy has announced his retirement from competitive cycling.

The 37-year-old Scot had been contemplating continuing until the 2014 Commonwealth Games in Glasgow, but has decided enough is enough and confirmed he was quitting the sport at a lunchtime press conference in Edinburgh today.

Hoy is Britain's most decorated Olympian after his haul of two gold medals at London 2012 saw him surpass rower Steve Redgrave's record of five.

Hoy said: "It was not a decision I took easily or lightly but I know it's the right time."
