Uphill hikes and downward dogs in the Black Mountains of Wales

A women's yoga and fell walking break in the Welsh borders leaves our writer with aching muscles but a heart full of joy

Bruce Chatwin was 15 when he first cycled through the Vale of Ewyas, a place he would later refer to as one of the emotional centres of his life". Wordsworth and Turner also loved this rough knuckle of mountains abutting the England-Wales border. I was 20 when I first visited, and was so smitten by the swooping hills that I leapt out of the car and ran barefoot up Hay Bluff, seized by a reckless delirium.

Two decades later I'm on a new yoga and fell walking weekend here, with Chatwin's beloved valley unfurling below. The packing list had included sun cream - but this is Wales, in winter, and the weather isn't playing ball. Rain pitter-patters on still-green leaves. Boots squelch in oily mud. Mist shrouds a seam of oaks.
