I decided to pre-make all of my food for the trip and send resupply boxes to myself every week or so. This requires much more preparation than the typical resupplying-in-town method, but I felt it was the most cost-effective and nutritious approach. I spent over a hundred hours shopping, chopping, cooking, dehydrating, vacuum sealing, and sorting food into boxes, which was the most stressful part of the preparation.
As for gear, I also spent about a hundred hours comparing and shopping online, taking multiple trips to different outdoor gear stores, trying to find the best deals, and fine-tuning my gear list.
Another part of my preparation was writing. I decided to apply for grants and gear sponsorships, write stories about my alternative path and why I was taking it, and reach out to people and companies for guidance on my undertaking. After countless revisions on emails, stories, and application essays, I finally finished and despite the stress it caused me, I was beyond happy with the outcome.
