12-Hours Race is an early Olympic track cycling endurance event contested over a fixed time period rather than a fixed race distance. Riders are ranked by the total distance completed within twelve hours, making the event a severe test of stamina, pacing, resilience, and the ability to manage fatigue over an extended continuous effort. Such extreme long-duration track races were characteristic of early cycling programmes and reflected the endurance-focused nature of nineteenth-century velodrome competition.
