Over the last two days I have been working with a group from Cotsworld outdoors. The first day I took the group out to learn all about GPS units that they stock in their stores. It was perfect weather for navigation, very low thick cloud. We tested the limitations of GPS units whilst testing out the new RAB range of clothing. Day 2 we went scrambling up the North ridge of Tryfan. The weather was much nicer today, clear skies and light winds. This meant we had a quick ascent, then went up Bristly Ridge (grade 1***) and back down to do a little introduction to ropework which the group may use on a scramble.
