I am going to be leaving for a JMT thru-hike on July 11, and am going for what is essentially a 15-day itinerary (it's technically 16, but my permit has me camping at the Little Yosemite Valley campground the first night, so the first day is a whopping 4 miles, which is less than I walk to work every day). This is going to be my first long-ish hike- my longest was the Wonderland Trail around Rainier at 93 miles, and the 40-50 mile range isn't completely foreign to me.
For a variety of reasons, my training plans have gone out the window- first due to some unexpected work issues having me work nights and weekends for a while, then a strange foot injury that kept me from getting out for a while and caused me to cancel a couple of weekend overnights. As it stands, I'll probably have 2 maybe three weekends where I can get in an overnight, and maybe three or four vacation days to play with to extend a weekend. Because of the outside issues messing with what I had planned, I've been out once since October.
So, with all of this lead-in, I'm curious if anybody has input on the conditioning/training aspect of preparing for something of a bit longer distance. Am I better off:
1. Sticking to weekends (i.e. do 3+ weekend trips), and trying to put a chunk of the vacation days together into one longer trip (70 miles or so)?
or
2. Breaking it up and trying to do a few (probably 2) "long weekend" style trips where I maybe knock out 40-50 miles over three days? These would be done in conjunction with a few weekend overnights as well.
Obviously, I know I'm asking questions that have a lot to do with personal preference, hiking style, etc., but in terms of building up my legs, and getting myself conditioned to get used to walking a decent distance everyday, I assume that there's some prevailing wisdom on the topic. In a perfect world, I'd have been a gym rat for the last few months and spent a lot more time on-trail, but it is what it is, and I want to make the most of the time I have left.
FWIW, I'm in Philadelphia and would be hiking primarily in places within a 4-5 hour drive.
