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.
On April 21, 1980, two days after his 40th birthday, he was the first masters finisher at the Boston Marathon, with a time of 2:25:25, good for 51st place overall.

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.
