The marathon was conceived centuries ago and as of recent has been gaining popularity among many populations around the world. The 42.195 km (26.2 mile) distance is a physical challenge that entails distinct features of an individual's energy metabolism. Marathon runners finish at different times because of individual physiological characteristics.
Human physiology dictates that a runner's near-top speed cannot be maintained for more than thirty seconds or so as lactic acid builds up, and leg muscles begin to be deprived of oxygen. [ 90 ] The 60 metres is a common indoor event and it an indoor world championship event.
The marathon is the only road running event featured at the World Athletics Championships and the Summer Olympics, although there is also the World Athletics Half Marathon Championships held every two years. The marathon is also the only road running event featured at the World Para Athletics Championships and the Summer Paralympics.

Running a marathon is no small feat, and as thousands of hopefuls hit the pavement this fall, many will be taking on the 26.2-mile distance for the very first time. For most, it’s a once-in-a ...
Endorphins are credited as the cause of the feeling of euphoria and wellbeing found in many forms of exercise, so proponents of this theory believe that the second wind is caused by their early release. [13]
Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis. [1] In athletics and track and field, sprints (or dashes) are races over short distances.
During a marathon, for instance, runners typically hit the wall around kilometer 30 (mile 20). [2] The condition can usually be avoided by ensuring that glycogen levels are high when the exercise begins, maintaining glucose levels during exercise by eating or drinking carbohydrate-rich substances, or by reducing exercise intensity.
