I'll just have to work it bit harder at it. I think I was holding back a bit as I was unsure of the route choice as a whole. By the way what are your usual split times for leg 1.

About 80/45 - your 42 sounds fast to me! - but then I dont try to run the mushy bits of the trod to and below hare crag.
Ill have a go at your cairn traverse of halls fell - assuming you can settle on whether it is SSW or SSE!
