A marathon is considered an aerobic dominant exercise, but higher intensities associated with elite performance use a larger percentage of anaerobic energy. The lactate threshold is the cross over point between predominantly aerobic energy usage and anaerobic energy usage.
Long slow distance (LSD) is a form of aerobic endurance training used in sports including running, [1] rowing, [2] skiing [3] and cycling. [4] [5] It is also known as aerobic endurance training, base training and Zone 2 training. [6]
ATP production via aerobic pathways can further be limited by glycogen depletion. [22]: 56–57 Free Fatty Acids serve as a sparing mechanism for glycogen stores. The artificial elevation of these fatty acids along with endurance training demonstrates a marathon runner's ability to sustain higher intensities for longer periods of time.
Running economy (RE) a complex, multifactorial concept that represents the sum of metabolic, cardiorespiratory, biomechanical and neuromuscular efficiency during running. [1]: 33 [2] [3] Oxygen consumption (VO 2) is the most commonly used method for measuring running economy, as the exchange of gases in the body, specifically oxygen and carbon dioxide, closely reflects energy metabolism.
Aerobic exercise, also known as cardio, is physical exercise [1] of low to high intensity that depends primarily on the aerobic energy-generating process. [2] " Aerobic" is defined as "relating to, involving, or requiring oxygen", [ 3 ] and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. [ 4 ]

As a result, it has become common to examine the factors that influence the energy cost of running in an attempt to predict or improve running performance. There are many factors that may affect the energy cost of running, including age, training, stride rate and frequency, shoe weight, wind resistance, and even air density. [7]
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.
