Six-time Olympic champion Sir Chris Hoy is expected to confirm his retirement today following a 13-year career.
Winner of six Olympic titles, 11 world titles and two Commonwealth crowns, the 37-year-old will formally end his career at a media conference at Murrayfield Stadium in Edinburgh.
Hoy competed in his final race on August 7 2012 at the Olympic Keirin final on the last day of the London 2012 track programme.
Hoy delivered with a victory which saw him overtake Sir Steve Redgrave as the Briton with the most Olympic gold medals.
