Why this is not a fitness ebook
The Multi-Day Hike Preparation System covers feet, footwear, load and friction, and says plainly that it is not a fitness programme. The Ascent Profile Audit reads your itinerary's altitude risk, and says plainly that it is not about fitness either. Both of those lines were already live before this system existed. This is the answer to them.
What a benchmark can and cannot tell you
A 3-minute step test and a loaded-comfort check decide where you start: standard pace, a slightly faster pace through Foundation, or a short block of extra preparation first. That is genuinely useful, and it is also the limit of what it does. It is not a medical fitness assessment, it does not predict whether you will complete your trek, and there is no invented single "readiness score" behind it, on purpose.
Two patterns, read from your itinerary
Some treks are many similar days in a row. Others are mostly ordinary days with one dramatically harder push. Weeks 9 and 10 train for whichever one your itinerary actually is, chosen from two questions about your own day-by-day schedule, not from a list of named destinations pretending to be a difficulty score.
