Although I understand savoring the planning process, I think four months is plenty of time to prepare for an AT thruhike. There may be moments where you’ll wonder if you can possibly get it all done in time – but that happens even when you have years to prepare.
For my first AT hike, I had about five months to seriously prepare - it was more than enough time. I bought the guidebooks, marked them up, bought my gear, trained, packed - and still had time to get nervous. My second AT hike, I had three weeks. It was hectic, but I was packed and stored in two. For the CDT, we had three years - more than enough time to memorize the guidebooks (not quite, but almost), but the last month was still insane because we had been taking our time since we had so much to spare. In January we still hadn’t started packing, our training was half-hearted, and I really wondered about our commitment to the hike. In March we got serious. We left in May. For the PCT we had the period between ending our CDT hike and starting for the PCT - about five months. We would have left in two if the weather had allowed.
Reality is, getting ready for a long hike isn’t that difficult. Buying gear can take some thought - or it can just be a question of buying what you can and dealing with the possibility that it isn’t ‘perfect’. (My AT gear wasn’t great - but it got me there.) Training can make your first weeks much easier - but you have four months to get in shape - that’s enough. Buying the guidebooks and figuring out a resupply strategy only takes a couple of weeks, if that. Do you have to dehydrate enough food for six months? Why not just do selective maildrops with your food, and buy the rest as you go. It’s much easier – especially if you have limited long distance hiking experience so don’t know whether your tastes will change after weeks on the trail. It happens to many, if not most, hikers.
As to whether you want to go - well that’s up to you. If you aren’t emotionally ready now, you may not be next year either. If you don’t really really want to be out hiking, then don’t do it. But if you yearn for the trail - then do what it takes to get out there.
I had the opposite problem: on at least two of my hikes, I was emotionally ready to go long before it was financially feasible to do it. Almost every day between April and November I thought, “I wish I were hiking.” Or “I can’t wait to be on the trail.” We started our countdown at about 500 days - now there are only 145 to go - and I still can barely stand the wait. I know how much we still have to do - a house to pack up and 10,000 details to take care of - but one way or another, we’re going hiking.
And just remember - you had it in your head to hike in 2007. You still can. But you can also hike in 2006 - and then either go back the next year, or go hike the PCT in 2007.
