Pat, as has been said many times on this forum the best focus for hours training is ups and downs rather than distance, time on feet rather than pure distance. I did much of my training for the rounds I have done in The Peak as opposed to The lakes. Multi ascents of kinder, up and down Whin Hill time after time etc. Living in S Manchester you have great access to The Goyt and Western edge of Kinder where all sorts of endless up and down fun can be invented. Also I don't think 10000 feet a week is necessary but to build up to that ability before your round and also have a few 10 hour days out is a key part of the build up. After that its psychological!!
