The end of a 10k is mentally more difficult to manage than that of a marathon, and the best strategy to avoid 'hitting the wall' is to constantly strive to accelerate.

The perceived difficulty of the 10k compared to the marathon is based on the nature of the effort: the 10k is run at an intensity close to VMA (Maximal Aerobic Speed), inducing a rapid accumulation of metabolites such as H+ ions (acidosis), which creates a sensation of intense muscular burning. Conversely, the marathon is an event of fundamental endurance where fatigue is more related to glycogen depletion and pace management over time. Research in sports physiology (such as that published in the 'Journal of Sports Sciences' on self-regulated effort) confirms that the brain plays a central role as a modulator, limiting performance to protect homeostasis. The advice to 'accelerate' is a recognized cognitive strategy for maintaining engagement and countering central fatigue, although its effectiveness varies according to the athlete's level. Asserting that one is objectively 'harder' remains subjective, as it depends on the individual's training specificity (anaerobic threshold vs. endurance). In short, the creator describes a physiological reality linked to the intensity of the effort, while proposing a mental tactic consistent with performance optimization practices.
