we assisted a fell runner who had slipped on wet rocks in the llyfnant valley and was unable to walk. This is just over the border for us, but as many of our team live close by, we were happy to help our friends at Brecon Mountain Rescue Team , and were able to reach the casualty in good time. The casualty had spare clothes, a blizzard bag, a method of raising the alarm for help, and had left a route plan behind, all of which helped. He was cold when we arrived but had he not come prepared with these items, he would have been in a worst state. We used a splint on the injured ankle, and transferred him onto our stretcher for the walk out of roughly a mile. We have since heard that he has been discharged from hospital with a spiral fracture to his fibular, but avoided the need for surgery. We wish the casualty a speedy recovery, and hope to see him back out on the trails soon, but upright next time!
