Even after realizing the desire, the future marathoner often faces internal resistance—the "Refusal of the Call." Fear, doubt, procrastination—all of this is natural. "Can I do it?", "Will I have enough time and strength?", "What if I fail?". The antidote to these thoughts is often a meeting with a mentor. In the context of a marathon, this could be an experienced coach, a running club, a group of like-minded people, or even a structured guide like this one. A mentor does not walk the path for you, but they provide wisdom, encouragement, and a proven plan, which significantly reduces the fear of the unknown.
