We got out with the guys from Mountain Fuel on Helvellyn's Edges this winter.
Helvellyn has it all, easy access, great trails and some eye-popping exposure; just don't slip!

We ran form The Swirls carpark by Thirlmere and headed up around Brown Cove Crags to drop down Swirral Edge and back over Striding Edge. Needless to say, care should always be taken, whatever the conditions, as the ridges are exposed and preciptious.
