Well I went back and did the Cumbrian Traverse in daylight.
Took 8:59 in glorious weather, fells very busy until Gable then met no one else.
My wife met me at road crossings pity I didn't pick up my food at three shire stone, had a coke/water and a banana there which I can tell you now is enough energy for two hours.
Started coming round after Honister even managed a sprint to the Moot hall to get under 9 hours (8:58:56)
Will have to do it again some time was a great day out.
