The Corn Du, Pen y Fan, Cribyn and Fan y Big loop is spectacularly, beautifully and horribly brutal. It’s essentially a really long assault on your legs, disguised as a scenic jaunt through the Brecon Beacons’ finest ridgelines.
It’s a gentle incline through Taf Fechan Forest. We’re going at a steady pace, our strides short, and my pigtails bouncing under my woolly hat (my mother, whenever she sees me like this post-run, asks me why I am dressed like a child). This feels fine so far. This might, I think, be an okay run today.
