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.
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 system – This is the long-duration energy system. After five minutes of exercise, the O 2 system is dominant. In a 1 km run, this system is already providing approximately half the energy; in a marathon run it provides 98% or more. [6]

Other physiological factors affecting a marathon runner's aerobic capacity include pulmonary diffusion, mitochondria enzyme activity, and capillary density. [ 22 ] : 4–5 A long-distance runner's running economy is their steady state requirement for oxygen at specific speeds and helps explain differences in performance for runners with very ...
The Eau Claire Marathon is an annual marathon that takes place in Eau Claire, Wisconsin in the United States. The race starts and finishes at Phoenix Park and features views of the Chippewa River . In 2023, RaceRaves announced the Eau Claire was the best marathon in Wisconsin based on feedback they received.
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]
The marathon is a long-distance foot race with a distance of 42.195 kilometres (c. 26 mi 385 yd), [1] usually run as a road race, but the distance can be covered on trail routes. The marathon can be completed by running or with a run/walk strategy. There are also wheelchair divisions. More than 800 marathons are held worldwide each year, with ...
