I'm about to embark on my first big two week trek and have always simply taken too much food and came with with the rest (often packing an extra day's worth!). I'll be at high'ish altitude (around 10k) doing 20 mile days. I'm 6'3" 215 and muscular'ish. I'm a furnace. I try to keep my calories to around 2k a day normally with some variation.
So my question is, given 125 cal/ounce food, how many pounds (or calories, I can convert) do you think I need a day?
Mike C.'s book tells me I should do 1.4ppppd to start, bumping to 1.7 for days 10-14. I guess my skepticism comes from a) being a big guy, b) doing a lot of miles.
What do you think?
