So is the coniston loop more technical …………….
If you mean the ‘tour de coniston’, which goes up through the quarries at Tilberthwaite, you’ve done the hardest bit already.
If you mean, as above, a route which goes up to Stephenson Ground, then Seathwaite, push up Walna Scar etc, then there is one rocky bit on the Seathwaite drop, and a couple of short sections on WS, but I wouldn’t say any of them are harder than Nibthwaite. The pushing bit will take longer than you think. If in doubt, start and finish in Torver, that will bring it down to 13 miles or so.
