Sir Chris Hoy: Won two more golds at the London Olympics.
Olympic cycling great Sir Chris Hoy is expected to announce his retirement at a media conference on Thursday.
The six-time Oympic gold medal winner, who turned 37 last month, is to appear before the press in his home city of Edinburgh.
Since adding two more golds to his haul in London last summer, Hoy has been wondering whether he should compete in the 2014 Commonwealth Games at the Sir Chris Hoy Velodrome in Glasgow.
However, Hoy will be 38 when that event gets underway and it looks like he has decided to call a halt to his remarkable career.
But it has also been suggested that he plans to announce his intention to compete in Glasgow and then retire immediately after that.
Hoy has already prepared for life beyond competitive action and, late last year, he announced he would be releasing a brand of bicycles bearing his name.
The Scot has competed at four Olympics, winning his first gold in the 1km track time trial in Athens in 2004.
He then won the Team Sprint, the Keirin and the Sprint in Beijing in 2008, before winning the Team Sprint and the Keirin once again in London.
Those last two golds saw him overtake Sir Steve Redgrave as the Briton with the most gold medals in Olympic history.
And Hoy was also named the Sports Personality of the Year for 2008 after his remarkable efforts in Beijing.
He said last November: "I'll make a decision by spring next year.
"I'll be getting back into training and racing in January in Australia to see how the body copes.
"It's about whether my body can hold on."
