Quick answers
The 60-second version
Snippet-ready answers to common questions. Use the calculator above for the numbers.
Should I train by pace for a trail 50K?
Usually not. Pace by effort and terrain, then use cutoffs as checkpoints. The goal is repeatable time on feet.
Do I need back-to-back long runs?
They can help, but they’re optional early. Start with one repeatable long session, then add back-to-backs when recovery stays stable.
Is this free?
Yes — download the PDF/CSV and use it as a planning map. The app adds adaptation and decision support when life happens.
Assumptions
What this tool assumes
- • This is a week-by-week plan summary (not a day-by-day calendar).
- • Trail specifics (vert, terrain, heat) change execution — pace by effort and practice hiking.
Limitations
What can break it
- • Does not account for your specific course profile or mandatory gear rules.
- • Cutoffs are often segment-based; verify on the official race site.
