Training the Body

I'm no stranger to endurance efforts, having a background in triathlon, marathons, and ultra distance, topping off at 50 miles.
The triple secrets of being able to complete any kind of endurance event are:
1. Taking the time to prepare your body through gradual increases of duration and intensity with periodic breaks in throughout.
2. Proper mental attitude, meaning both the confidence that you will be successful and having a plan of how you will handle things when they go wrong.
3. Proper nutrition and hydration. Too few calories at too much effort and your body makes you stop. And of course, we need water, even more than food.
This post will focus on preparing our bodies for the task at hand. Here's the general training strategy:
1. Weekly mileage increases should, on average, be around 10%, working towards a target of a single hike equal to the anticipated longest day of hiking (about 16 miles) and a longest run of a bit more than half of that (actually, I have a 10 mile run planned for late March near the Delaware Water Gap that should be pretty exciting for the two of us). Our final pre-trip hike is scheduled on a 16+ loop from Hell (well, actually around Hell, MI).
2. Amount of weight carried will be added by about 25% at a time, reaching 100% within 4 weeks of the trip.
3. Physical activities will include hiking with equipment, running, body awareness exercises, and strengthening.
