Start with the owner-specific decision
Download a 100K schedule only after confirming repeatable running, a familiar long run, event-relevant terrain access and enough recovery around key weekends. The PDF cannot make a from-zero jump safe.
The plan should progressively connect time on feet, terrain, fueling and equipment without turning every long session into a race simulation.
Use a bounded readiness check
- Audit weekly frequency and long-run familiarity.
- Map safe terrain and equipment access.
- Schedule early fueling tests.
- Protect recovery after specific weekends.
- Use two stable weeks before progressing duration.
Hold, progress or adjust
Progress when long-run recovery, fueling tolerance and terrain movement remain stable. One exceptional weekend is weaker evidence than several repeatable weeks.
Reduce secondary duration, terrain difficulty or optional intensity first. Do not stack missed long runs or use the PDF to override pain and severe symptoms.
Compare distances in the ultra plan hub and use the exercise-and-sleep routine to protect recovery around long sessions.
The attached sources provide population or sport-specific evidence, not a guaranteed finish, diagnosis or medical clearance. Stop for acute illness, severe symptoms or pain that changes normal movement and seek appropriate care.
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.
