Endurance, or stamina, is measure differently depending on what is being referred to. The theory, or concept, of endurance has a different meaning for different activities. For example, endurance in relation to aviation is the amount of time an aircraft can stay in flight with a specific amount of fuel. Non-athletic endurance refers to the amount of continual patience required for a stressful activity. A prisoner-of-war would demonstrate this type of endurance.


Endurance in relation to exercise involves sustained medium to low impact activity for long periods of time, such as cross country running, marathon running or competing in triathlons. In endurance exercise, muscle fatigue is not what determines an activity's end. Instead, things like the need for sleep or the completion of the activity determine the end.


Endurance in relation to equestrian sport involves distance races run by a horse and its rider. Popular horse races in the United States include the Kentucky Derby, the Preakness and the Belmont Stakes.


Endurance in relation to auto racing refers to long distance races equaling at least 1000 kilometers. These events can last over 8 hours and many drivers share the driving responsibilities in such races. The most popular of these events is the 24 Hours of Le Mans. In the United States, the 24 Hours of Daytona (Florida) and the 12 Hours of Sebring are well-attended races.
