Looking forward to doing this in December, and I'm going for a 2-day recce next week. Any hints welcome from anyone who's done it. In particular, between CP 1 & 2, the route description says up Boredale and over the hause. Looking at the map, another possibility is to go to the N and W of Place Fell, on a footpath beside the lake. A little further but flatter. Would that be permissible? Would it be considered unsporting? Or is it like orienteering, where you have free choice between the checkpoints?
