Six-time Olympic champion Sir Chris Hoy is to hold a media conference in his home city of Edinburgh on Thursday where he is expected to announce his retirement.
Hoy, who was 37 last month, has spent the period post-London 2012 deliberating over his future, with the 2014 Commonwealth Games in Glasgow a major carrot.
The Scot will be 38 by the time competition commences at the Sir Chris Hoy Velodrome.
Privately figures in British Cycling have known for some time that Hoy, who won his first Olympic gold in Athens in 2004, is preparing to retire after four Olympic Games and a British record six gold medals, including two in the capital last August and three in Beijing in 2008.
Hoy has already prepared for life beyond competitive action and late last year announced he would be releasing a brand of bicycles bearing his name.
