Some good ones there. Done the way of the roses, lon las Cymru, eskdale and trough of bowland several times. All very different. Eskdale has a short flattish section and then before you know it you are heading up hard knot. Bowland is very local and a great ride. I enjoyed way of the roses as it has lots of family connections but lon las Cymru is a great touring route, probably the best of the UK sustrans routes.
