A known route fills the distance and the altitude. A custom hike uses the numbers you type. You will see week 1 before anyone asks for a card.
Big-Hike Prep is a conditioning schedule, not medical advice, not a guide service, and not a permit. Verify the route, permits, water, and closures with the land agency. Turn around for storms, altitude illness, or a missed turnaround time. Glaciated mountains need skills this plan does not teach.
