The other week I had someone ask me why I do this. Why I voluntarily hike for hours just to swim through freezing water and struggle through obstacles, and then hike some more.
Long answer: I do it for the challenge. I do it to prove to myself that I'm capable of accomplishing hard things. There's just something beautiful about waking up early and hiking for hours before the sun comes up. Something raw about pulling my cold, soggy body out of potholes when I'm not sure if I have the strength... then doing it five more times. Something rewarding about being able to problem solve and execute technical skills while fighting exhaustion. And then when I think I've reached my absolute limit, hiking for a few more hours. By the end, you're in pure survival mode and there's something so human about it. Something that compels you to ignore the bruises and sore muscles and discomfort in order to experience something few others ever will.
Short answer: Ever heard of Type 2 fun? 😜
