The fatigue during prolonged running is most likely associated with the depletion of glycogen stores in the muscles.

Here's a step-by-step explanation:

1. When you start running, your body first uses oxygen to break down carbohydrates, specifically glucose, for energy. This process is called aerobic metabolism.

2. The glucose used in aerobic metabolism comes from the glycogen stored in your muscles and liver.

3. As you continue to run, your body gradually depletes these glycogen stores.

4. Once the glycogen stores are significantly depleted, your muscles will start to fatigue and your pace will slow down. This is because your body needs to switch to using fat for energy, which is a slower process.

5. Therefore, the fatigue you feel during prolonged running is most likely associated with the depletion of glycogen stores in your muscles.
