So, we've decided to hike the Te Araroa, a 3000km trail that stretches from Cape Reinga at the northern tip of New Zealand, to Bluff, at the southern tip. How did we get here? What made us decide to walk away from our lives and into the wilderness for six months? Sleeping on the ground, getting eaten alive by bugs, carrying everything we need to survive on our backs, and going without showering for days at a time... we've done this for a couple of weeks at a time before, but five or six months? What are we thinking?
