The Wall (hitting it)
[thuh wawl (hih-ting it)]
/ðə wɔl ˈhɪtɪŋ ɪt/
Noun
The point during endurance exercise when an athlete experiences a sudden loss of energy and fatigue due to glycogen depletion.
The Wall refers to a sudden fatigue and energy depletion during endurance events, often around mile 20 in a marathon. It occurs when glycogen stores are exhausted, forcing the body to rely on less efficient fat metabolism. This results in a dramatic slowdown and mental struggle. Runners can delay or avoid hitting the wall by proper pacing, carbohydrate loading, and fueling during the race. Real-world examples include marathoners slowing significantly or even stopping. Understanding and preparing for the wall is crucial for maintaining performance and achieving race goals.
