Ever wondered what would happen if you tried to walk in a completely straight line across an entire country? No? Well i did. I thought about it a lot in fact, and in the winter of 2018/19 I decided i'd give it a go. The country i chose to traverse was Wales. 33 miles of mountains, farmland, lakes, rivers, and forests, and just the right amount of human activity and natural hazards to ensure regular doses of paranoia and pain. This week sees me leave the fields and venture into epic forests and mountains and attempt to cross Lake Vyrnwy in my cheapo inflatable Kayak without a life jacket.
