I plan to walk from Chiang Rai to Chiang Mai in approximately five days. Twenty-five miles a day, more or less, would get me to Chiang Mai in five days. Anything can happen though, so who knows, maybe I'll get to Chiang Mai in four days (doubt it), maybe it will take a week. Along the way, I'll need food and water, and since I wish to document the trip, a camera, memory cards, extra storage space, microphone, batteries, cables, power bank, wet wipes, a toothbrush, toothpaste, and a tent. There is more, but this is off of the top my head.
I have started the list of items I'll need and in order to do the walk and film the journey, I'll need far more things than I want to bring to be safe and a little comfortable. Each item, each piece of paper, plastic, metal adds weight, which will take its toll on my body. The more weight I carry, the more energy it takes to move forward. To make sure I only bring what is necessary, I made the first draft of what I think I'll need for the journey. I'm sure I can eliminate some of these items by departure day.
