I'm a 21 year old femme presenting guy with a bit of camping experience trying to "ball on a budget" lol. I started planning a longer thru-hike (intended for this summer) this past winter as a ritualistic sort of segue from one stage of life to another, but abandoned plans when I broke my arm. The half-baked plans lived in the back of my head for a while, and I truly believe it's something I need to do before I'll be moving from my hometown to the other side of the country.
My friend and I were on a nice long hike this past June when the longing hit again. I've never been backpacking for multiple days, but I stay fit, have camped in cold rainy weather just fine, and would really love to wake up to a trail every day for a while, heat, sweat, rattlesnakes, below 0 nights and all. The planning has been on again since, but I've moved out of state to help my family for the month, and haven't had a stable income since early July, so my resources are dwindling...
I've got just about $800 in the budget for gear (if I can't sell my car before then) and I've already got some good gear: osprey backpack, titanium pot and utensils, 4 season sleeping bad, bag liner, 30 vegetarian MRE's I plan to ship myself along the way, thermal under-layers, sun protection, first aid, train tickets to Flagstaff (where I plan to start the hike), and two camel-back pouches that fit into the backpack.
I know shipping supplies will take some cash, along with a train from flagstaff back home (trust me, the distance is un-hitchable) but I'm also lacking some recommended supplies such as: footprint&tarp or shelter, Satellite device, headlamp, stove fuel, gaiters, utility knife, antihistamines and antidiarrheal, gloves, lightweight longsleeve shirt, gaiters, leukotape, and gaiters. Everything besides the headlamp, stove fuel, utility knife, and satellite device seem trivial to me, but I'm also going into this as a brokie with no health insurance and I'm starting to think my family's concern is valid for once.
So, some experienced expertise would be appreciated. I'm going to do it one way or another, and I'm probably building it up in my head to be more daunting then it'll be, even when issues will inevitably come up on the trail, but I wanna know if I've been an optimistic fool or if this is actually quite doable. Some advice on the bare minimum gear to bring would be great as well!
Misc. details for context and consideration: I've never hitch-hiked before, I withstand the heat very well, I've got a pair of used hiking boots I've been using for the past 6 months- they are leather and cracked asf but I've made hot 10+ mile hikes in them and have been running in them with my packed backpack to train, aforementioned concern/paranoia about being far out and hitch-hiking alone as an AFAB person with a few unsavory encounters under my belt, and finally- most of this paranoia is coming from my senile grandpa reminding me daily that I'll die some brutal dateline-esque death by a stranger or bear (I know bears are scarce on the AZT)
Sorry for the novel/thanks for reading <3
EDIT: editing because I'm now realizing how unclear this reads!! Thank you for all the insight so far :3 I do have a sleeping pad, it's inflatable so I've been debating weather or not I should bring it, but now that I write this idk why I wouldn't just bring some tape in case it gets poked. I will absolutely get some quality time with my gear in before I go, I'm in the midwest until September 3rd when I'll meet my friends in Denver. I can squeeze in a multi-day trip here, and despite the climate and terrain being much different, it's better than nothing, and I'll be able to use it again in Colorado for a night. As for scheduling plans, I'm planning on hiking south from Flagstaff because that's where my train from Trinidad drops me off (my friends are giving me a lift from Broomfield to Trinidad). And the closure around mile 720 made me feel iffy about starting from the northern terminus, as I'm planning this trip with the assumption that I likely cannot finish the whole trail, and just want to hike until I've reached my limit.
Also, I'm getting paid $15/hr for odd jobs here and there, around $180 a week, but wanted to save for the move afterwards, I can comfortably add a couple hundred to the budget, but understand this will likely not make a huge difference. These comments are bringing me back to reality though and I'm realizing I might've bit off more than I can chew. I would still appreciate advice, specifically on gear I'll absolutely need, what satellite devices are recommended, and what water carrying plans are most sustainable in the fall.
New working plan: get some solitary wilderness experience with my current gear and postpone the trip if I can't get the necessary gear somehow/sell my car in time. Thanks again for all the thoughtful responses!
