Run or Die

Not sure if this is the right fit?

Consider Ultramarathon Man by Dean Karnazes.

“Ultramarathon Man (Dean Karnazes) reads like a firsthand logbook of an extreme “50 marathons, 50 states, 50 days” undertaking, written to keep you moving through spectacle and resolve. Its useful part is the momentum: you get the day-to-day drive, the mental grit, and the public-facing push toward taking “next steps” at any fitness level. The limitation is that it leans motivational and story-forward rather than technical. If you want training plans, physiology, or careful explanation of method, you may find the focus too broad.”
