Use the PDF as a schedule draft, not a fixed prescription
A 100K training-plan PDF is most useful when it turns a race date into a visible sequence of base work, long-run specificity, recovery, and taper. Downloading the file does not establish readiness. Before choosing a start week, record your recent repeatable volume, longest recent outing, trail and climbing access, injury or illness context, and the days that can reliably hold longer work.
Audit the plan against your course
Do not copy another athlete's weekly distance into the spreadsheet. Mark every session as essential, supportive, or optional. When travel, illness, pain, or life load removes capacity, drop optional work before stacking missed sessions.
Make the spreadsheet adaptive
Each week, record completed duration, terrain, perceived effort, sleep opportunity, symptoms, fueling practice, and next-day function. Change one major load variable at a time. A back-to-back weekend can be useful specificity, but it is not mandatory proof of toughness and should not leave normal movement impaired for several days.
Use the ultra training hub for plan-length options, the ultra cutoff planner for checkpoint arithmetic, and the 100K drop-bag plan for race-specific logistics.
Safety boundary
Stop and seek qualified care for chest pain, fainting, confusion, severe breathing difficulty, or pain that changes normal movement. The PDF is educational and not medical advice, a diagnosis, or a guarantee of finishing.
