The body has limited stores (~80-100 grams) of ATP, only enough to supply energy for two seconds of maximal sprinting; therefore ATP must be continually be resynthesized from other sources through different metabolic pathways. The 100-meter sprint utilizes both PCr and glycogen as fuel.
Third Energy Source When Running a Marathon: The Aerobic System. The aerobic system can use carbs, fats, or proteins to produce energy. Energy production is slower, however more efficient than the other two systems. As you can inform by the name, the aerobic system requires that there be adequate oxygen offered to the working muscles.

This is important: If the body consistently relies on protein for fuel, muscle protein stores will begin to decrease along with lean body mass, which can be detrimental to performance . This highlights the importance of fully replenishing glycogen stores after intense workouts, as well as on a daily basis.
Carbohydrate and fat are the primary sources of energy, with protein contributing a minimal amount under normal conditions. Adenosine triphospate (ATP) is the body’s usable form of energy. The body uses 3 different systems of metabolism to transfer stored energy to form ATP.
Energy is stored in the body in various forms of carbohydrates, fats, and proteins as well as in the molecule creatine phosphate .

Hopefully the following explanation of glycolysis will help you picture what is going on. Glucose is the only fuel that can be used during glycolysis, which literally means the breakdown of glucose . This breakdown creates ATP as glucose is converted into 2 molecules of pyruvate. Now:
One big reason for having adequate fuel before a workout, as well as on a daily basis, is to prevent the use of protein as a fuel source. Protein is usually spared from being used as an energy source and is used predominately by the body for tissue maintenance, growth, and repair.

This breakdown creates ATP as glucose is converted into 2 molecules of pyruvate. Hydrogen is also produced during this process and if oxygen is present, the aerobic system (explained next) can use hydrogen and pyruvate to produce more ATP.

The sprint system provides enough energy for a five to six second running sprint and doesn’t require oxygen (anaerobic). CP (creatine phosphate) is another high energy molecule where the phosphate can be broken off very quickly, so releasing energy and used to convert ADP back to ATP.
Anaerobic running energy. The high power system provides energy for a 90 second running power burst. This system is the fast anaerobic (without oxygen) breakdown of glucose for energy but only provides two molecules of ATP along with a waste product called lactic acid which can cause muscle fatigue.
It is wrong to think though that this means you should just fuel you running by eating fat. The preferred energy fuel for the muscles is glucose. Glucose is formed from the breakdown of carbohydrates in your diet and is stored as glycogen in the muscles and liver. However, there is a limit in the amount of glycogen the body can store, ...
Here are the key sources of that energy. When energy is required, the body breaks up a substance called ATP (adenosine triphosphate), a high energy molecule consisting of three phosphates attached by energy bonds to adenosine. Energy is released by breaking off a phosphate from ATP to form ADP (adenosine diphosphate).

There are three systems in the body that create ATP energy. These systems work simultaneously but the contribution from each depends on the type of exercise, its intensity and duration.
Aerobic running energy. The endurance system is about how long you can keep going and depends on how fit you are. This system is the slow aerobic and uses oxygen. The breakdown of glucose for energy provides a massive 38 molecules of ATP — nearly 20 times more than the anaerobic system. The aerobic system can also use fat to produce ATP energy.
During a race the marathon runner uses approximately 75 kilograms of ATP, and as this amount cannot be stored in the body ATP is resynthesized from different fuels (i.e. PCr, carbohydrates, lipids and protein), with the catabolism of the fuels providing the energy required.
For the body to perform exercise for any given intensity or duration it requires energy. Energy is provided chemically in the form of Adenosine Triphosphate (ATP), a high-energy phosphate stored within skeletal muscle. ATP is the only fuel that can be used directly by the working muscles for contraction.
There are three different energy systems in the body: 1 The Immediate System - Fuelled by the intramuscular high-energy phosphates ATP and Phosphocreatine (PCr); 2 The Short-Term System - The anaerobic glycolysis (glycogenolysis and/or glycolysis) or lactate system; fuelled by glycogen, glucose, and the glycerol backbone of triglycerides; and 3 The Long-Term System - The aerobic glycolysis and oxidative phosphorylation of the macronutrients carbohydrate, lipids and protein (Maughan, et. al., 1997; McArdle, et. al., 2007).
The 100-meter sprint utilizes both PCr and glycogen as fuel. There is enough PCr in the leg muscles to provide half the ATP needed for the race. Glycogen therefore provides the other half of the energy required.
The 100-meter sprint is an explosive, maximal race lasting about 10 seconds. The immediate and short-term energy systems are utilized to anaerobically chemically regenerate ATP from intramuscular stores of PCr and glycogen respectively during the race.

The body has limited stores (~80-100 grams) of ATP, only enough to supply energy for two seconds of maximal sprinting; therefore ATP must be continually be resynthesized from other sources through different metabolic pathways.
Carbohydrates are metabolized through glycolysis, a process that can be both anaerobic (conversion to pyruvate or lactate) and aerobic (continuation through metabolic pathways as pyruvate converts to Acetyl-CoA and enters the Krebs cycle and electron transport chain for oxidative phosphorylation).
