Unlike its two-wheeled counterparts, track cycling is an entirely indoor discipline in which athletes race around a 250m wooden velodrome, which houses steep banks that rise to 42 degrees in parts.
Events are split between sprint and endurance with competitors racing either in teams or as an individual. The discipline featured at the first ever Games in the modern era at Athens 1896.
Team GB have enjoyed unprecedented levels of track cycling success in recent Games, winning seven gold medals at both Beijing 2008 and London 2012, helping GB amass 60 medals since Athens 1896.
With six golds and one silver to his name, Sir Chris Hoy is the most successful Olympic track cyclist of all time with Sir Bradley Wiggins close behind on six medals – though has a seventh via his time trial efforts at London 2012.
