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. If i were to succeed, i would surely be the first recorded person to carry out such a feat, acquiring the accolade of having walked the shortest distance across Wales in the process. Would i make it all the way to the Mawddach estuary at Penmaenpool? and would i actually be able to stay glued to the line at all times? or would i have to sacrifice a few metres in order to avoid being seriously injured, or worse, confronted by an angry welsh farmer?—Tom Davies
