I have got my eyes on the Derwent Watershed walk. Not the continuous 24 hour marathon you understand, which is surely madness, but a more "leisurely" 2 day walk with a wild camp at around half way.
I have covered most of the route over the years in a series of day walks and realise that this will be a tough outing, ( I enjoy a challenge).
I have the walk pencilled in for a weekend in mid to late September.
If anyone on the forum has done either version of the walk I would welcome your shared experiences.
